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.”

At 67, Canadian runner Pete Benson is preparing to take on one of the most extraordinary endurance challenges in marathon running: completing seven marathons across seven continents in just seven days while raising money for a cause that reaches far beyond the finish line.

Hailing from Grand Manan, New Brunswick, Benson is set to participate in the Great World Race, an ambitious event that combines the physical demands of marathon running with a demanding journey around the globe. The challenge will require him to complete seven full marathons, each covering 42.195 kilometres, while travelling between continents on a tightly scheduled itinerary.

The challenge is scheduled to begin on November 15, 2026, with pre-event activities expected to start around November 12. Benson's adventure will begin in Antarctica, where the icy terrain and harsh conditions will provide a formidable introduction to the week ahead.

The opening marathon is scheduled for Wolf's Fang in Antarctica, where Benson will face the unfamiliar and potentially unforgiving conditions of the frozen landscape. Reflecting on the prospect of running through the ice and snow, he admitted that the experience is intimidating.

"That's pretty, pretty scary in itself," he said. "Through the ice and snow."

From Antarctica, Benson will travel to Cape Town, South Africa, for his second marathon on November 16. The journey will then continue to Perth, Australia, on November 17, followed by Singapore on November 18. On November 19, he is scheduled to race in the Algarve, Portugal, before heading to Cartagena, Colombia, on November 20. The challenge will conclude in Miami, United States, on November 21.

The demanding itinerary will leave little time for conventional recovery. After each marathon, Benson will need to travel to the next destination, navigate changing time zones and prepare for another 42.195 kilometres. Managing fatigue, nutrition, hydration and sleep will be essential as he attempts to complete the seven races within a single week.

Benson described the unusual routine that awaits him, highlighting the relentless cycle of running and travelling that defines the challenge.

"We run the race, get back on the bus, back on the plane, head to the next one and away we go around the world," Benson said. "That plane becomes our hotel and restaurant for the week, pretty much."

Beyond the physical demands, Benson recognises that taking part in such an ambitious international adventure comes at a considerable financial cost. He describes running as a personal investment, one that has provided him with valuable experiences and opportunities to discover more about himself.

"It's certainly a want, not a need," he said. "Some people go on river cruises and other things that they spend their money on and I spend my money on running and I've learned a lot from it."

Despite the expense, Benson believes the experience is worth the investment.

"So I think the investment is worth it, but it is extravagant," he said.

However, his motivation extends beyond personal achievement. Benson is also using the challenge to raise money for a nonprofit organisation that funds clean-water projects in countries around the world. The fundraising initiative is voluntary and is not a requirement for participating in the event.

By connecting his running adventure to a cause with a tangible impact on communities, Benson hopes to give every kilometre a greater purpose. His effort demonstrates how an individual sporting challenge can also become an opportunity to support work that improves lives.

"I'm happy that there's a purpose behind every mile that I run," he said.

That purpose adds another dimension to Benson's ambitious undertaking. While the seven marathons will test his physical strength, mental resilience and ability to recover between races, his fundraising mission will allow him to contribute to efforts aimed at improving access to clean water around the world.

As November 15 approaches, Benson is preparing for a demanding week that will take him from the ice and snow of Antarctica to the streets of Miami, with five other destinations in between. Each marathon will bring a new test, requiring careful preparation, determination and the ability to keep moving forward despite accumulating fatigue.

At 67, Benson is setting out to complete an extraordinary endurance challenge while supporting a cause beyond himself. Seven marathons, seven continents and seven days will test his limits, but his journey will carry a purpose that extends far beyond the finish line.

Australian endurance athlete Mick Marshall has achieved an extraordinary milestone at the 2026 Marine Corps Marathon in Washington, D.C., setting a world record for the fastest marathon completed on crutches after crossing the finish line in an incredible 5:35:50.

Representing Altra as an elite athlete, Marshall demonstrated remarkable determination and perseverance throughout the 26.2-mile (42.195-kilometre) race, turning one of the world's most celebrated marathon events into a stage for an inspiring display of human resilience.

Completing a marathon is a demanding physical challenge for any athlete, requiring months of preparation, mental strength and the ability to push through fatigue. Covering the same distance on crutches presents a different set of challenges, placing considerable demands on the upper body, coordination and endurance. Marshall's achievement highlights the dedication required to overcome obstacles and pursue goals that many might consider beyond reach.

The Marine Corps Marathon, renowned for its patriotic atmosphere, enthusiastic spectators and scenic course through the nation's capital, provided a memorable setting for the record-breaking performance. As thousands of runners pursued their own finish-line goals, Marshall carved out a special place in the event's history with his remarkable effort.

Beyond the record itself, Marshall's achievement carries a message that resonates far beyond the running community. Every movement toward the finish line required determination, patience and an unwavering commitment to the challenge before him. His performance is a reminder that greatness is not measured solely by how quickly someone reaches a destination, but also by the courage it takes to pursue a goal despite the difficulties along the way. For aspiring athletes and anyone facing personal challenges, his accomplishment offers a powerful lesson in perseverance, self-belief and the importance of refusing to give up when the journey becomes difficult.

His performance also serves as a reminder that marathon running is about far more than finishing times and podium positions. It is a test of courage, commitment and the willingness to redefine personal limits. Marshall's accomplishment demonstrates that the spirit of distance running extends beyond conventional expectations, inspiring athletes and spectators alike to reconsider what is possible through determination and hard work.

Marshall's remarkable run also reinforces the inclusive spirit of distance running, where the finish line belongs to everyone willing to take on the challenge. Whether competing for a championship, chasing a personal best or simply striving to complete the distance, every runner has a story worth celebrating. By setting a world record on crutches at one of America's prominent marathon events, Marshall has added an unforgettable chapter to that story, encouraging others to look beyond perceived limitations and pursue their ambitions with renewed confidence.

For Marshall, the 5:35:50 finish represents more than a time on the clock. It marks an extraordinary personal achievement and a moment that celebrates perseverance, resilience and the determination to keep moving forward. His performance has brought renewed attention to the remarkable possibilities within endurance sport and the many different ways athletes can challenge expectations.

Marshall's achievement at the Marine Corps Marathon stands as a powerful testament to the human spirit, demonstrating that success is not always about having the easiest path, but about finding the strength to keep going. His 5:35:50 performance is a reminder that the finish line can represent much more than the completion of a race: it can symbolise courage, possibility and the extraordinary things people can accomplish when they refuse to give up.

The 23rd edition of the Standard Chartered Nairobi Marathon delivered a spectacular celebration of endurance, determination and competitive excellence on Sunday, October 25, 2026, as Abraham Kiptum and Mercy Kandie Rotich claimed the men's and women's 42km titles in a memorable showcase of Kenyan road-running talent.

With thousands of runners taking to Nairobi's Southern Bypass, the full marathon provided a compelling test of physical strength, tactical discipline and mental resilience. For the elite athletes at the front, every kilometre presented an opportunity to gain an advantage, while the demanding distance required unwavering concentration from the starting gun to the finish line at Uhuru Gardens.

In the men's race, Kiptum produced an impressive performance to secure victory in 2:10:35, narrowly missing the course record by just 23 seconds. The 37-year-old Kenyan demonstrated his experience and endurance throughout the contest, ultimately establishing himself as the strongest performer over the 42.195-kilometre distance.

Kiptum's victory was particularly significant given his recent return to competitive marathon running. The athlete from Kapsabet had continued rebuilding his career and arrived in Nairobi following victory at the CRDB International Marathon in Dar es Salaam, Tanzania, in August. His latest triumph provided another encouraging chapter in his return to the forefront of distance running.

The men's contest produced an exceptionally close battle for the remaining podium positions. Fellow Kenyan Amos Kipkemoi Cheruiyot finished second in 2:10:37, just two seconds behind the champion, while Mark Kibiwott secured third place in 2:11:05.

Dismas Kiplimo finished fourth in 2:11:15, followed by Henry Kiprono Togom, who completed the top five in 2:11:55. The depth of the leading performances underlined the quality of competition on a morning when the front-runners pushed each other towards impressive finishing times.

Kiptum's performance also highlighted the importance of consistency and preparation in marathon running. Having invested months in training, the experienced Kenyan delivered when it mattered most, navigating the course with the composure required to emerge victorious against a competitive field.

The women's 42km race was equally captivating, with Mercy Kandie Rotich claiming the championship in 2:31:25 after a determined performance over the challenging distance.

Rotich demonstrated resilience and composure as the race unfolded, maintaining her challenge through the later stages before securing the victory. Her performance earned her a place among the latest champions of one of Kenya's prominent annual road-running events.

The battle for the women's title was decided by the narrowest of margins. Peris Jerono finished second in 2:31:27, only two seconds behind Rotich, while Ruth Wakabu completed the podium in 2:31:36. The three leading women finished within just 11 seconds of one another, providing a dramatic conclusion to the contest.

Shyline Jepkorir placed fourth in 2:34:55, while Dorothy Kipkilach finished fifth in 2:36:38, rounding out the leading performers in the women's division.

The narrow margins between the leading athletes reflected the unpredictable nature of marathon racing, where pacing, endurance and the ability to respond under pressure can determine the outcome after more than 42 kilometres of competition.

Beyond the podium battles, the full marathon represented a celebration of the determination that defines long-distance running. Every athlete who took on the distance faced the challenge of managing energy, overcoming fatigue and maintaining the mental strength necessary to reach the finish line.

The Southern Bypass provided the setting for these performances, with the runners navigating the Nairobi course before completing their challenge at Uhuru Gardens. The event brought together elite competitors and recreational athletes, united by the ambition to test their limits over the classic marathon distance.

The 2026 edition once again demonstrated the enduring appeal of road racing in Kenya, a country internationally recognised for producing exceptional distance runners. It also offered a platform for athletes to pursue personal ambitions, compete for prestigious honours and showcase the depth of talent within Kenyan athletics.

For Kiptum and Rotich, however, the day belonged to the pursuit of victory. Their respective performances secured them the coveted men's and women's marathon crowns, while the fiercely contested podium finishes ensured that the 42km races delivered the drama and excitement expected of a major road-running championship.

As the 23rd Standard Chartered Nairobi Marathon concluded, the achievements of the two champions stood out as the defining moments of the full-marathon competition, celebrating not only speed and endurance but also the preparation, perseverance and competitive spirit required to conquer 42.195 kilometres.

The true spirit of marathon running was beautifully displayed at the 2026 Mainova Frankfurt Marathon, where the celebration extended far beyond the elite athletes who crossed the finish line first. In a heartwarming tradition, the race's men's and women's champions waited inside the historic Festhalle Frankfurt to welcome the final finisher, reminding the world that every marathon journey deserves recognition.

As the final runner entered the magnificent venue, the atmosphere transformed into an unforgettable celebration. Confetti filled the air as music, dazzling lights and a red-carpet welcome created a moment usually associated with the sport's biggest stars. Standing alongside the champions, the last finisher received a hero's reception, demonstrating that the achievement of completing a marathon deserves to be celebrated regardless of finishing position.

Ethiopia's Jirata Lelisa Dinki, who won the men's race in an impressive 2:05:26, and compatriot Zeineba Yimer Worku, the women's champion in 2:19:45, were among those celebrating the final runner's remarkable achievement.

Their presence sent a powerful message about the values that make marathon running special. While elite athletes push the limits of human performance in pursuit of victory and fast times, thousands of other runners take on the same 42.195-kilometre challenge for deeply personal reasons. For some, the goal is to achieve a personal best; for others, it is to overcome adversity, fulfil a lifelong ambition or simply reach the finish line.

The final finisher's journey may have taken longer than that of the champions, but the determination required to keep moving forward deserves equal admiration. Every kilometre represents effort, sacrifice and perseverance, and crossing the finish line marks the successful completion of a challenge that demands both physical endurance and mental strength.

Frankfurt's special welcome captured an essential truth about distance running: a marathon is not only a race against the clock but also a personal battle against exhaustion, doubt and the temptation to give up. By waiting for the final runner, the champions helped ensure that the day's celebrations included someone whose achievement might otherwise have gone unnoticed.

In a sport often defined by world records, course records and podium finishes, this touching tradition offers a refreshing reminder that the value of a marathon cannot be measured by time alone. The fastest runners may make headlines for their performances, but every finisher has a story worth telling.

At the Mainova Frankfurt Marathon, the champions had already conquered their own challenges. Yet their decision to welcome the last runner created another memorable moment, showing that greatness in sport is measured not only by what athletes accomplish but also by the respect they show others.

Because when the final runner receives the same warmth, applause and celebration as the champions, the message is unmistakable: every runner matters, every finish line represents an achievement, and nobody should be left behind when it is time to celebrate.
