Ultrarunners and coaches share their best advice for building mileage without getting injured.

Whether you want to progress from a 5K to a half marathon or a marathon to an ultra, a few general rules on how to run longer can help you get there.

While building mileage and time on your feet is paramount, the key to doing it successfully involves patience and persistence. “As much as volume matters—volume is king—too much volume too soon can get you on the sidelines,” Bertrand Newson, RRCA-certified run coach and founder and team captain of Too Legit Fitness, based in San Jose, California, tells Runner’s World. 

Follow these tips from Newson and other coaches and ultramarathoners to successfully increase your mileage, avoid injuries, and crush your longest distances.

1. Build a Base, Then Keep It Consistent

“I steadily built up to running 250-mile races over many years, but I started by running one mile at a time,” says Sarah Ostaszewski, pro ultrarunner with Tailwind Nutrition who won the 2023 Ouray 100-Mile Endurance Run. “Build a strong base and try to keep a consistent running routine, so then adding a little extra here and there won’t seem so daunting.” 

Base training typically requires about four to eight weeks (before following a race training schedule) to strengthen your cardiovascular system and your muscles, but the longer you can regularly run and set a foundation, the better. Your base work should involve mostly easy runs, low mileage, and maybe low-key speedwork (depending on your fitness level), like ending a run with strides. This part of your training is all about consistency, rather than actually building mileage. 

Ultrarunner Mirna Valerio stays consistent by focusing on time on her feet, rather than distance. “This has been mentally freeing,” the author of A Beautiful Work in Progress tells Runner’s World. 

“I have a standing appointment with my treadmill a couple times a week,” says Valerio, who will aim to run a minimum of 12 hours a day over six days at the Lululemon Further event, an ultramarathon for women in March. “I just get it done, which incidentally is one of my mantras.”

2. Find Your Best Approach to Building Volume

If you’re new to running and want to run longer, add another day of a short, easy run to your schedule, suggests Stefanie Flippin, an ultrarunner, Lululemon ambassador, and doctor of podiatric medicine, who has earned a first-place finish at several 100-milers.

Maxed out on available days of the week? Add to your long-run mileage, which is what Leah Yingling, ultrarunner and biochemical engineer who will see how far she can run in 24 hours at Lululemon Further, does first when aiming to build volume. The general rule is to increase your weekly mileage by about 10 percent each week, adding to that long run. For example, if you currently clock 17 miles per week with three four-mile runs during the week and a long run of five miles on the weekend, you would keep your midweek mileage the same, but kick up your long run to about seven miles next weekend.

Yingling, and many other pros, also do two runs a day. While this won’t work for everyone, if you don’t have a significant single block of time, clocking some miles in the morning and again in the evening and resting between can help you clock more mileage. One must-do to make it work: Tame the intensity on at least one of those runs.

Charlie Lawrence, 50-mile world record holder, views his second run of the day as a sort of active recovery. He often goes for double digits in the mornings, then runs for about four miles (at minimum) in the evening, keeping the effort light. 

No matter what, testing out strategies to see what works for your schedule is the best way to run longer. “That might be adding a walk a few days a week in addition to your daily runs, or maybe you’re adding back-to-back long runs,” says Yingling. “Whatever you do, find something that is sustainable.”

3. Follow a Progressive Training Plan

A good training plan will slowly build mileage to decrease your risk of getting sidelined, as research shows taking on too many miles too soon is one of the biggest risk factors for overuse injuries. 

When choosing your training plan, you have to be realistic about the time you have to build up to the distance you want to conquer—and where you’re at now, says Newson. For example, if you have your sights set on a half or full marathon, think about what you can comfortably run today. Then, following the loose rule of adding 10 percent more miles each week, how long do you need to train? If you currently run five miles without stopping and feel good after, and can comfortably clock 12 miles per week, you can probably conquer a 10-week half marathon plan. 

Another important factor to look for when it comes to mileage on a training plan: recovery weeks. Newson explains you’ll typically see this as three weeks of building, then a week in which you back off mileage a little to give your body time to recover and actually make gains from all the work you put into your plan. This will also keep your body strong and help you sidestep aches and pains, he adds.

4. Keep Easy Runs Easy

You’ve heard it before but it’s especially true when trying to run longer: Don’t overdo your low-effort days. 

“It’s important for me to always run my easy runs, short or long, at a conversational, aerobic rate of perceived exertion. This means that I can easily chat with a training partner for the duration of my runs without becoming out of breath,” Flippin says, who also clocks her heart rate to make sure she’s in an easy zone. 

Don’t worry about what shows on Strava, either. “I think a lot of runners run their easy runs too hard and that is because of ego and they don’t want people to think they are slow,” says Devon Yanko, ultrarunner who’s placed first in several 100-mile races and will aim to conquer her longest distance over six days at the Lululemon Further event. “I delight in the idea that people may look at my Strava and think I am too slow, because on race day that won’t be the case!” 

More generally, applying the 80/20 rule to your training overall can also help you record more low-intensity runs, Newson says, as it means 80 percent of your workouts should happen at a low intensity, and 20 percent at a hard effort.

It’s these easy runs that will help keep you running consistently—the key that unlocks higher mileage. “A B+ average of consistent runs, strength work, and recovery measures stacked over weeks, months, and years will always trump sporadic A+ weeks followed by a total drop-off,” Flippin says.

5. Master the Long Run

For most people, the long run will make up the bulk of your weekly mileage, but it doesn’t just help you clock more time on your feet. It also teaches you mental stamina, how to deal with fatigue, and it can help you get comfortable with being uncomfortable. With years of practice, this is what many pros say pulls them through farther distances.

Even though Lawrence can deal with being uncomfortable for long periods of time, he still turns to mind games to mentally check off miles. For example, he often breaks a race down into small, manageable chunks, often focusing on the next fuel stop (typically about every four miles) as a check point. If he’s struggling to get to the next four-mile marker, he may tell himself he’ll feel better in 10 to 15 minutes and checks in again then. 

In addition to breaking your long run up into segments, Newson also suggests dedicating each mile to someone else, which takes it outside of yourself and gives you another reason to keep going, and says to focus on the mile you’re in, simply putting one foot in front of the other. 

Finally, the long run is the perfect time to practice your fueling and fluid intake, Newson says, considering you need energy to clock longer miles. Aim to take in carbs when going for 90 minutes or longer, and go for about 30 to 60 grams per hour after the first hour. 

6. Schedule a Few Harder Workouts

To build endurance, you want to run long, but you can also add intervals and speed work into your schedule. 

Lawrence gets on the track for VO2 max-specific workouts at least once a week. VO2 max is the amount of oxygen you can take in while running and is a major marker of fitness—the better this metric, the easier running will feel, which will help you go longer with less effort. Focusing on VO2 max intensities on runs means going for about 90 to 100 percent of your max heart rate or about 5K pace, and it could involve intervals like 400-meter repeats. 

You could also focus on lactate threshold training. Your lactate threshold is the point at which your body produces lactate at a rate you can no longer clear, leading to fatigue. To help you prolong that side effect—helping you go faster for longer—practice running at your threshold pace. (Here’s how to calculate your running speed at lactate threshold). 

To do this, Ostaszewski prefers longer interval workouts with work periods ranging from six to 10 minutes near aerobic threshold. But tempo runs at your threshold speed are also smart. 

7. Supplement Your Runs With Mobility and Strength

Before you jump into high mileage, you need a solid warmup. Lawrence has been doing the same activation drills before runs for a long time. He starts with foam rolling most of the lower body, then does a series of exercises, like:

Leg swings

Down dog to lunge rotation

Ankle mobility moves

Banded work, like glute bridges

This go-to routine wakes him up and gets him in run mode, even when he’s not feeling it. 

Cross-training workouts are also key. Valerio mixes strength training, mobility workouts, Pilates, and rowing into her training schedule, which she says helps her avoid overuse injuries. Meanwhile, Flippin points to strength training in particular as crucial to running longer. She suggests starting with one day a week to build consistency, then adding on days from there. 

Lawrence focuses specifically on doing core workouts every day (one of his go-to moves: the ab roll out), along with dedicated gym time for lifting, in which he conquers moves like hex bar deadlifts.

8. Make Recovery a Priority

Many pro runners turn to a solid nutrition practice to jumpstart recovery and fuel future performances. “I ensure I’m always getting in carbohydrates and protein within 30 minutes of finishing a key workout or long run,” Yingling says.

Finding time for other recovery practices, like mobility work, foam rolling, even meditating, can also support your training and get you prepped for the next round of mileage, Newson says. Full rest days are also important, especially if you’re feeling any aches and pains.

And you can’t forget about sleep for recovery—striving for at least the recommended seven to nine hours—especially for those looking to push their mileage. 

9. Don’t Rely on Motivation Alone

Running your longest distance takes dedication and determination, but don’t expect to feel motivated every day. “People often wait to do things until they are motivated, when instead, they should have been focused on completing their plan or working toward their goal,” says Yanko. “I don’t jump out of bed every morning peppy and excited to run, but I am committed to doing the work and thus, I simply get the work done.”

Yanko also suggests tapping into curiosity to keep you going longer. “That is, instead of being intimidated by a workout or long run, I allow myself the opportunity to be curious about what might happen if I simply begin the session,” she says. “I do not believe that one workout or one long run ‘proves’ anything about my fitness or ability to race, so having curiosity means I can get into a session and allow it to unfold with confidence that if I just continue to show up and do the work, I will build my fitness brick by brick.”

Newson also suggests a running group to keep you accountable and consistent, and to elevate the fun of your workouts. 

“On the mental side, I always try to see the big picture and remember that all the miles I’m running are for fun and for my own personal enjoyment,” Ostaszewski adds. “I’m always aiming to enjoy the process and recognize growth in the journey.”

Ethiopia delivered a remarkable double victory at the 2026 Bank of China Hong Kong-Zhuhai-Macao Bridge Half Marathon on Sunday, November 15, with Wede Kefale and Addisu Gobena emerging victorious in the women's and men's races respectively.

Staged along the spectacular Hong Kong-Zhuhai-Macao Bridge, the event brought together some of the finest distance runners from Ethiopia, Kenya, South Africa and other nations for a fiercely contested 21.097-kilometre challenge across one of the world's most recognisable sea-crossing structures.

The competition produced impressive performances, with Ethiopia showcasing its depth in distance running while Kenyan athletes also secured several places among the leading finishers.

In the women's contest, Kefale produced a composed and determined performance to secure the biggest prize of the day. She crossed the finish line in 1:09:01, holding off a strong challenge from South Africa's Glenrose Xaba, who finished second in 1:09:09. Ethiopia's Fantu Worku completed the podium in 1:09:14, making it an exceptionally close battle among the leading three women, who were separated by just 13 seconds.

The Ethiopian victory was particularly impressive given the quality of the field. Xaba, one of South Africa's leading distance runners, pushed hard throughout the contest but ultimately had to settle for second, while Worku demonstrated Ethiopia's remarkable strength by securing another podium position.

Kefale's victory was supported by an impressive Ethiopian presence throughout the top 10. Baraky Redae finished fourth in 1:09:51, followed by compatriot Asmarech Anley in fifth with 1:10:21. Kenya's Miriam Chebet was sixth in 1:11:05, ahead of Morocco's Fatima Ezzahra Birdaha, who clocked 1:11:23. Kazakhstan's Daisy Jepkemei placed eighth in 1:11:42, while Ethiopia's Zewudie Wudu finished ninth in 1:12:08. Kenya's Priscah Jepleting Cherono completed the top 10 in 1:12:29.

The men's race provided another memorable moment for Ethiopia as 22-year-old Addisu Gobena claimed the overall victory, He clocked 1:01:33 to finish ahead of compatriot Aliyi Kasim, who secured second place in 1:02:29.

Kenya's Alex Lenalepisho delivered a strong performance to take third in 1:02:47, preventing a complete Ethiopian sweep of the men's podium. Morocco's Othmane El Goumri finished fourth in 1:03:07, while Kenya's Abel Kiplimo followed in fifth with 1:03:33

Kenyan representation remained particularly strong throughout the men's top 10. Ezra Kipketer Tanui finished sixth in 1:05:32, followed by Ethiopia's Tafere Adisu in seventh with 1:05:35. Kenya's Meshack Kipchirchir placed eighth in 1:06:01, Benard Kipkorir was ninth in 1:06:15, and compatriot Sena Ledama completed the top 10 in 1:06:21.

Gobena's triumph adds another impressive achievement to Ethiopia's growing presence on the international road-running circuit, while the performances of Kasim and Lenalepisho underlined the competitive depth of the men's field.

The 2026 edition was also significant for the event itself, having earned World Athletics Platinum Label status, placing it among the highest-rated road-running competitions internationally. The bridge provided a spectacular setting for the contest, bringing together elite athletes from different countries for a memorable day of long-distance racing. 

Beyond the podium, the results highlighted the international character of the competition, with athletes from Ethiopia, Kenya, South Africa, Morocco and Kazakhstan featuring prominently in the leading positions.

Ethiopia therefore left Hong Kong with both overall titles, while Kenya had plenty of reasons to take encouragement from its strong representation across both races.

For the organisers, the successful staging of this Platinum Label competition represents another important milestone in the development of road running in Hong Kong. For the athletes, it was an opportunity to test themselves against international opposition on a distinctive course that offered a memorable backdrop to the racing.

American sprint sensation Noah Lyles could be preparing to chase one of the most extraordinary achievements in athletics history after dropping a tantalising hint about his ambitions for the 2027 World Athletics Championships in Beijing, China.

The four-time world 200m champion has sparked excitement among athletics fans after sharing a cryptic message on social media reading “4x ? 2027”, raising speculation that he could be targeting an unprecedented four gold medals when the global championships return to the iconic Bird’s Nest Stadium.

Although Lyles has yet to confirm exactly which events he intends to contest, the possibility of a four-event campaign has become particularly intriguing following World Athletics’ announcement that the mixed 4x100m relay will make its World Championships debut in Beijing.

Such an opportunity could open the door for the American superstar to compete for gold in the men's 100m, 200m, men's 4x100m relay and the newly introduced mixed 4x100m relay.

For Lyles, Beijing could represent much more than another opportunity to add to his impressive collection of championship medals. It could be the stage where he attempts to establish himself as the most successful male athlete in World Athletics Championships history.

The 100m would undoubtedly be one of his biggest attractions. Having claimed the world title in Budapest in 2023 before completing his remarkable rise to Olympic glory at the Paris 2024 Games, Lyles knows exactly what it takes to rule the world's premier sprinting stage. However, he will be eager to reclaim the global crown after settling for bronze behind compatriots in the 2025 World Championships in Tokyo.

The 200m, meanwhile, remains his strongest territory. Lyles has established an extraordinary legacy over the half-lap distance, winning four consecutive World Championships titles in 2019, 2022, 2023 and 2025. In Tokyo, he matched Usain Bolt's remarkable achievement of four successive world 200m crowns, further strengthening his reputation as one of the greatest performers the event has ever witnessed.

His ambitions would also extend to the relays, where he has repeatedly demonstrated his value to Team USA. Lyles has already collected four World Championships gold medals in the men's 4x100m relay, including victories in 2019, 2022, 2023 and 2025. Another successful campaign in Beijing would provide an opportunity to add to that impressive record.

The introduction of the mixed 4x100m relay could make the challenge even more fascinating. With the event officially scheduled to make its World Championships debut in Beijing, the competition will offer another opportunity for the world's leading sprinters to showcase their speed on the global stage.

Beyond the possibility of four gold medals, however, there is an even bigger historical prize waiting for Lyles.

The American currently boasts eight World Athletics Championships gold medals. Winning four more in Beijing would take his career tally to 12, moving him beyond Jamaican sprint legend Usain Bolt, whose 11 world titles remain the benchmark for male athletes in the competition's history.

That would be a remarkable achievement for an athlete who has never hidden his admiration for Bolt and his desire to reach the heights established by the Jamaican legend.

Interestingly, the Bird's Nest Stadium carries its own special place in sprinting history. It was at the same venue during the 2008 Beijing Olympic Games that Bolt announced himself to the world with his breathtaking performances in the 100m, 200m and 4x100m relay. Nearly two decades later, the iconic stadium could provide the setting for another extraordinary chapter in sprinting history.

For Lyles, the challenge will be enormous. Successfully navigating four demanding events, managing the competition schedule and delivering at the highest level across individual and relay races would require exceptional preparation, consistency and teamwork.

Nothing has yet been confirmed regarding his participation in all four disciplines, but his intriguing message has certainly given athletics followers something exciting to anticipate.

Could Beijing 2027 become the championship where Noah Lyles transforms an ambitious dream into an unforgettable reality?

Four events, four potential gold medals and the possibility of surpassing one of the greatest sprinting legends of all time. The countdown to Beijing promises to be fascinating.

What began as one of the most entertaining and talked-about stories of the 2026 New York City Marathon has taken an unexpected turn, with Houston-based lawyer Andrea Sager losing her official race result after a viral video showed her smoking marijuana during the event.

The 35-year-old mother of two attracted widespread attention on November 1 when she lined up for the iconic 26.2-mile race wearing a bright pink running vest carrying a humorous personal advertisement: “Andrea, 35, Single. Great Credit. Bad Judgment.” The unusual message quickly made her one of the most recognizable personalities among the thousands of participants, generating plenty of reactions from spectators and social media users.

However, it was another moment captured on camera that eventually landed her in trouble with race organizers. A video circulating online showed Sager accepting a puff of marijuana from a spectator while running along the marathon course, turning what had initially been a lighthearted appearance into a much bigger controversy.

Following the circulation of the footage, New York Road Runners (NYRR), the organization responsible for staging the marathon, removed Sager's finishing time of 5:54 from the official results after determining that she had violated its Code of Conduct. The regulations prohibit smoking, vaping and the use of tobacco or marijuana products in the starting corrals, along the course and within the designated race areas.

Despite the disqualification, Sager was allowed to retain her physical finisher's medal, meaning she still has a memento of completing the demanding journey through New York's five boroughs, even though her official finishing result no longer stands.

Sager has since offered an explanation for her decision, revealing that she was struggling physically as the race progressed. With considerable discomfort in her legs and the marathon becoming increasingly difficult, she said she accepted the offer from a spectator in an attempt to manage the pain and make the remaining miles more bearable.

Interestingly, the controversy has not entirely dampened her enthusiasm for the experience. Rather than retreating from the attention, Sager has embraced the unexpected publicity, revealing that the viral moment has brought considerable interest on social media and dating platforms.

Her distinctive pink running vest has also become a talking point beyond the marathon, with the attention opening up potential opportunities for merchandise and brand partnerships inspired by the memorable message.

Although she initially challenged the decision, Sager has acknowledged that the organizers were enforcing their regulations and appears to be taking the outcome with a sense of humour. She has also indicated that she could return to the marathon distance in the future, suggesting that her New York experience may not be her last.

For Sager, the 2026 New York City Marathon will undoubtedly be remembered for reasons far beyond the challenge of covering 26.2 miles. She arrived at the starting line hoping to enjoy her first marathon and perhaps attract a little attention with her unusual outfit. Instead, she left with a viral story, unexpected publicity and a disqualification that has made her one of the most talked-about recreational runners from this year's event.

Her finishing time may have disappeared from the official results, but her story has certainly found a place in the conversation surrounding this year's marathon.

After all, completing a marathon is an achievement in itself, but Andrea Sager's New York experience came with a twist that few runners could have anticipated!

World mile record holder Josh Kerr has sparked an interesting conversation among runners after questioning the growing popularity of hydration vests, suggesting that many athletes may be carrying more equipment than they actually need for their everyday training sessions.

The British distance-running star shared his thoughts during a Reddit Ask Me Anything session hosted by BBC Sport on Monday, where he responded to questions from fans about training, competition, rivalries and some of the lighter aspects of his life as an elite athlete.

Among the most relatable topics was the increasing use of hydration vests, a piece of equipment that has become increasingly common among recreational runners, particularly those who head out for regular training sessions.

Kerr offered a straightforward perspective, suggesting that runners covering distances of less than 12 miles (approximately 19 kilometres) generally do not need to carry water with them. He believes that some running trends are driven more by marketing than genuine necessity, using hydration vests as an example of equipment that has perhaps become more popular than it needs to be.

He further pointed out that runners training in urban environments can usually find somewhere to purchase a drink if they need one, rather than carrying additional equipment throughout their entire run.

However, his comments were not intended as a universal rule for every athlete. Hydration requirements differ depending on individual needs, weather conditions, training intensity and the distance being covered. Runners tackling longer distances, particularly in hot conditions or on remote trails, may still benefit considerably from carrying their own fluids.

Away from the equipment debate, Kerr also addressed questions about his relationship with Norwegian distance-running superstar Jakob Ingebrigtsen. Keeping his response brief and humorous, the Briton remarked, "I wouldn't say we're buddies!" However, he acknowledged that rivalries are an important part of athletics and can help make the sport more exciting for competitors and spectators alike.

The 2024 Paris Olympic Games also featured prominently in the discussion, particularly the men's 1500m final, where Kerr secured the silver medal in a British record of 3:27.79 behind American Cole Hocker.

Despite narrowly missing out on Olympic gold, Kerr insisted that he had no regrets about how he approached the race, reflecting the confidence and competitive mentality that have helped establish him among the leading middle-distance runners in the world.

The Scottish star also offered fans a glimpse into the demanding training sessions behind his remarkable mile world record, providing insight into the preparation required to compete at the highest level. He additionally touched on the possibility of eventually moving up to the marathon, a prospect that will undoubtedly attract considerable interest given his credentials over shorter distances.

Not every question, however, was about world records, Olympic medals or gruelling workouts. In one particularly amusing moment, Kerr was asked how far he thought he could run on just a single square sausage and a can of Irn-Bru, bringing a distinctly Scottish flavour to the conversation.

The exchange offered a refreshing look at the personality behind one of Britain's biggest athletics stars, showing that even athletes operating at the very highest level have plenty of opinions about everyday running habits.

For recreational runners, Kerr's message about hydration vests is certainly worth considering, although individual circumstances should always determine what equipment is necessary. His broader point was simple: runners should understand their actual training needs rather than automatically following every new trend in the running industry.

Kenyan marathon star John Korir is preparing to chase a remarkable piece of history at the 2026 Valencia Marathon, where victory could make him the first male athlete in more than two decades to successfully defend the prestigious title.

The 30-year-old, who will celebrate his birthday just four days before the December 6 race, returns to Spain with an opportunity to achieve something that has proved exceptionally difficult in the history of the competition. Having conquered the Valencia streets last year in an outstanding 2:02:24, Korir now has his sights firmly set on becoming a two-time consecutive champion.

A successful defence would place Korir in an exclusive group of athletes who have managed to win Valencia's men's marathon twice. The race's historical records identify only three previous multiple winners: Teodoro Pérez, Eduardo Alcaína and Samuel Tangus. Tangus remains the last man to achieve consecutive victories, having triumphed in 2002 and 2003.

Korir's opportunity has become even more promising following the withdrawal of Ethiopian star Yomif Kejelcha, who was ruled out of the December 6 contest because of an injury. Kejelcha had been among the biggest attractions in the anticipated showdown. His absence removes a major challenger and leaves Korir as one of the leading favourites heading into the race.

The Kenyan's recent performances explain why expectations are so high. He has established himself among the world's most formidable marathon runners, collecting major victories in Chicago in 2024, Boston in 2025, Valencia in December 2025 and Boston again in April 2026. His latest Boston triumph was particularly impressive, as he successfully defended his crown in a spectacular course-record time of 2:01:52.

However, Korir is not returning simply to defend his title. He has much bigger ambitions, with reports indicating that he is targeting a historic sub-two-hour performance on Valencia's famously fast course. To prepare for that challenge, the Kenyan has reportedly increased his training volume to between 250 and 270 kilometres per week, demonstrating the scale of preparation behind his ambitions.

Breaking the two-hour barrier would be an extraordinary achievement, particularly on a course where the current men's record stands at 2:01:48, set by Ethiopia's Sisay Lemma in 2023. Korir already knows what it takes to deliver a major performance in Valencia, having produced a commanding victory last year.

Turning 30 just days before the competition, Korir appears to be entering an exciting period of his marathon career. His combination of experience, consistency, confidence and remarkable endurance makes him a serious contender not only for another victory but also for a possible assault on the course record.

For Korir, December 6 represents an opportunity to go beyond another major marathon victory. He could end a 23-year wait for a consecutive men's champion in Valencia, join an exclusive group of multiple winners and potentially deliver one of the fastest marathon performances ever witnessed.

The challenge is now clear: defend his crown, make history and perhaps bring the world closer to another landmark moment in marathon running.
