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.”

The future of American distance running may have just announced itself.

Luke Surface, an 8th-grade student-athlete from North Raleigh Christian Academy in Raleigh, North Carolina, delivered a performance that stunned the track and field community after taking on some of the nation’s best high school runners at Nike Outdoor Nationals.

Competing at the legendary Hayward Field in Eugene, Oregon — one of the most iconic venues in American distance running — Surface lined up in the boys championship 5,000 meters against a field dominated by high school seniors, including several athletes preparing to compete at the NCAA Division I level.

Despite being one of the youngest runners in the race, the 14-year-old held his own against the elite competition, finishing eighth in an incredible 14:25.88. The performance set a new national middle school record, averaging approximately 4:39 per mile for more than three miles.

That kind of time is fast enough to win many high school state championships across the United States and meets qualifying standards for several major NCAA Division I conference competitions — a remarkable achievement for a runner who has not yet entered high school.

But Surface’s historic 5,000m performance was only the latest chapter in a season filled with record-breaking moments.

Earlier in May, he clocked 8:52.03 for 3,200 meters at the NCISAA Division I State Championships in North Carolina, breaking another national middle school record. His converted two-mile time of 8:55.12 surpassed the previous world-best mark for a 14-year-old age group, previously held by Vincent Recupero.

During the previous cross-country season, Surface also made headlines when he ran 15:12 at the adidas XC Challenge, finishing second while competing against runners who were several years older.

Across cross country, two miles, and the 5,000 meters, Surface has continued to prove that his talent is far beyond his age group. While he still has four years of high school competition ahead before reaching the college level, his performances have already placed him among the most exciting young distance runners to watch.

The American high school 5,000-meter record currently stands at 13:32, set by Lex Young in 2023 — a mark Surface is not yet close to challenging. However, his remarkable progression at such a young age has caught the attention of the running world, with many eager to follow how far his extraordinary journey can go.

For now, Luke Surface remains an eighth grader rewriting the record books — and his story is only beginning.

DOHA, Qatar – Ethiopian distance running is once again making a powerful statement on the global stage. Following the Doha Diamond League meeting, Ethiopia has achieved a remarkable clean sweep of the women's 3000m/5000m standings, occupying all eight leading positions in one of the most competitive disciplines in world athletics.

Leading the charge is Likina Amebaw, who sits comfortably at the top of the rankings with 22 points. Close behind is fellow Ethiopian star Freweyni Hailu on 14 points, while Medina Eisa occupies third place with 12 points. The dominance continues through the rest of the leaderboard, with Senayet Getachew, Hawi Abera, Aleshign Baweke, Marta Alemayo, and Bernesh Dessie completing an extraordinary Ethiopian monopoly of the standings.

The achievement highlights Ethiopia's exceptional depth in women's distance running, where a new generation of athletes continues to emerge and challenge for global honours. Rather than relying on a single standout performer, Ethiopia has assembled a formidable squad capable of controlling races and collecting points across multiple Diamond League meetings.

While the current standings paint a picture of complete Ethiopian supremacy, the battle for the Diamond League title is far from over. Several meetings remain on the road to the season finale, leaving plenty of opportunities for rivals to close the gap and for positions within the Ethiopian contingent to shift dramatically.

For now, however, the spotlight belongs firmly to Ethiopia. The East African powerhouse has transformed the women's 3000m/5000m standings into an all-Ethiopian affair, sending a clear message to the rest of the world that the race for Diamond League glory will likely run through Addis Ababa.

The question now is whether Likina Amebaw can maintain her advantage and finish the season as the overall leader, whether Freweyni Hailu or Medina Eisa can mount a successful challenge, or whether another athlete will produce a late-season surge to rewrite the script.

One thing is certain: the road to the Diamond League Final promises a fascinating battle among some of the finest distance runners on the planet.

Jake Wightman delivered a masterclass in championship racing as he surged to the men's 800m title at the UK Athletics Championships, holding off a determined challenge from Ben Pattison in a thrilling finish.

In a race defined by patience, positioning, and precise execution, Wightman waited for the perfect moment to strike before unleashing his finishing kick down the home straight. The former world champion crossed the line in 1:45.40, just doing enough to edge Pattison and secure the national crown.

The contest lived up to expectations, bringing together two of Britain's finest middle-distance talents in a tactical battle where every move carried significance. With the pace controlled through the early stages, the field remained tightly packed, setting the stage for a dramatic final lap.

As the bell rang, the intensity immediately rose. Pattison looked poised to seize control and pushed hard in the closing metres, but Wightman's experience and race awareness proved decisive. Drawing on years of competing at the highest level, he maintained his composure under pressure and found the extra gear required to stay ahead when it mattered most.

The victory marks another significant chapter in Wightman's decorated career and serves as a timely statement of intent as the international season gathers momentum. More importantly, it showcased the qualities that have made him one of Britain's most respected middle-distance athletes — tactical intelligence, resilience, and an ability to deliver in the biggest moments.

For Pattison, the narrow defeat will provide encouragement rather than disappointment. His performance confirmed his growing status among Britain's elite 800m runners and highlighted the depth of talent currently thriving in the event.

But on this occasion, the spotlight belonged to Wightman. In a race where the margins were razor-thin, he executed his plan to perfection and walked away with the UK Athletics Championship title.

Remember the name Gout Gout.

At just 18 years old, the Australian sprint prodigy is already commanding global attention and fueling conversations about the future of track and field. In a sport constantly searching for its next superstar, Gout is rapidly emerging as one of the brightest talents the world has seen in years.

His latest statement came at the prestigious Ostrava Golden Spike meeting, where he stepped onto the track alongside some of sprinting's biggest names, including reigning world champion Noah Lyles. Far from being overwhelmed by the occasion, the teenager delivered a composed and confident performance, finishing third in the 150m in 14.96 seconds against two of the fastest athletes on the planet.

Yet impressive as that performance was, it is not the result that has the athletics community buzzing most.

Earlier this year, Gout stunned the sprinting world by clocking an astonishing 19.67 seconds for 200m, setting a new world Under-20 record. The performance instantly elevated him from promising prospect to genuine phenomenon.

What makes the achievement even more remarkable is the historical context. At the same age, Gout was faster than sprint legend Usain Bolt. Comparisons to the Jamaican icon are inevitable, not because records demand them, but because the raw numbers are impossible to ignore.

Of course, Gout's journey is only beginning. Like any young athlete, he still has room to grow, refine his craft, and gain valuable experience at the highest level. The road from teenage sensation to global champion is rarely straightforward.

But there is no denying the extraordinary potential that lies within him.

His speed, composure, and ability to perform under pressure have already marked him out as one of athletics' most exciting young stars. More importantly, he possesses the kind of talent that inspires belief that a new era of sprinting may be on the horizon.

The sport has always thrived on rivalries that capture the imagination of fans across the globe. With established champions such as Noah Lyles currently leading the way, the emergence of Gout Gout adds an intriguing new chapter to sprinting's future.

The next great rivalry may already be taking shape.

And one of its leading figures is still only a teenager.

For now, the message is simple: remember the name Gout Gout. The future is arriving faster than anyone expected.
