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.”

Long before he became the fastest man in history, before the Olympic gold medals, world records, and global superstardom, Usain Bolt was simply a gifted teenager with extraordinary speed and limitless potential. In 2002, on the track at Kingston's National Stadium in Jamaica, the world witnessed the first chapter of a story that would forever change athletics.

At just 15 years old, Bolt lined up for the men's 200 metres at the World Junior Championships with the weight of expectation resting on young shoulders. Competing before a passionate home crowd, the Jamaican prodigy produced a performance that instantly captivated the athletics world. Crossing the finish line in 20.61 seconds, he became the youngest athlete ever to win the men's 200m title at the championships.

It was far more than a gold medal. It was the moment the world realised that a once-in-a-generation talent had arrived.

Bolt's victory in Kingston marked the beginning of one of the greatest careers in sporting history. Over the years that followed, he rewrote the record books, dominated the Olympic Games and World Championships, and transformed sprinting into a global spectacle through his breathtaking speed, infectious personality, and unrivalled confidence. His legacy continues to inspire young athletes across the globe, many of whom dream of following the same path he once began as a teenager.

This week, that dream comes alive once again as the World Athletics U20 Championships take centre stage at the iconic Hayward Field in Eugene, Oregon. The venue has already witnessed the birth of future superstars. In 2014, it was where Britain's Dina Asher-Smith and Uganda's Joshua Cheptegei captured their first global titles, launching careers that would later produce world championships, Olympic medals, and lasting legacies in athletics.

Twelve years later, another generation arrives in Eugene hoping to create its own defining moment.

Among the brightest young talents is Great Britain's Jake Odey-Jordan, the 200m bronze medallist from Lima who now owns the European U20 100m record after an astonishing 10.01-second performance. He enters the championships eager to build on his growing reputation as one of Europe's most exciting young sprinters.

The United States will look to Tate Taylor, who has already made history as the first American high school athlete to break the 20-second barrier for the 200 metres. Fresh from a Diamond League victory in a sensational 19.75 seconds, he arrives in Eugene carrying the momentum of one of the most remarkable junior seasons ever recorded.

Jamaica, the nation that introduced the world to Usain Bolt, will once again have high hopes through Shanoya Douglas. The talented sprinter has established herself as one of the championship's leading contenders after producing lifetime bests of 10.98 seconds for the 100m and 22.11 for the 200m this season.

History has repeatedly shown that the World U20 Championships are far more than a junior competition. They are often the first chapter in the careers of future Olympic champions, world record holders, and global icons. Every generation arrives with ambitious dreams, but only a select few leave having announced themselves to the world.

No one can say with certainty whether the next Usain Bolt will emerge this week. Greatness cannot be predicted, and legends are never manufactured. Yet every legendary career begins with a single breakthrough performance.

For Bolt, that defining moment came in Kingston in 2002.

Now, under the famous lights of Hayward Field, another group of gifted teenagers stands ready to chase history. Somewhere among them could be the next athlete whose name will inspire the world for years to come.

"An athlete cannot run with money in his pockets. He must run with hope in his heart and dreams in his head." More than seventy years after those words were spoken, they remain among the most powerful messages ever shared in distance running. They are often quoted as simple motivation, but behind them lies a remarkable story of sacrifice, courage, conviction, and an unwavering belief that true greatness is never measured by financial reward.

Few athletes have left a legacy as enduring as Emil Zátopek. Known around the world as "The Czech Locomotive" for his relentless determination and unmistakable running style, he redefined what was possible in endurance racing. His legendary performance at the 1952 Olympic Games in Helsinki still ranks among the greatest achievements in athletics history. In the space of just nine days, he captured Olympic gold in the 5,000 meters, the 10,000 meters, and, incredibly, the marathon—a race he had never attempted before.

Yet the world in which Zátopek competed was vastly different from today's professional athletics landscape. During the 1950s, elite sport officially operated under strict amateur rules. Olympic athletes were forbidden from accepting prize money or earning a living directly from competition, although unofficial financial arrangements existed in many sports. Zátopek himself never raced for appearance fees or lucrative prize purses. Instead, he served as an officer in the Czechoslovak People's Army, receiving a military salary while representing his country. Running brought him glory, but not personal wealth.

It was within that environment that his famous words carried genuine meaning. For Zátopek, success was never driven by the promise of money. He believed the greatest performances were fueled by hope, ambition, discipline, and the courage to pursue dreams that seemed impossible. Those qualities, rather than financial incentives, formed the foundation of lasting excellence.

With the benefit of history, his words carry even greater significance. In 1968, during the Prague Spring, Zátopek openly supported democratic reforms in Czechoslovakia. When the movement was crushed, he paid a heavy personal price for standing by his principles. He was stripped of his military rank, removed from public life, and forced into years of manual labor. The man who had once stood proudly atop the Olympic podium found himself performing physically demanding jobs, far removed from the stadiums where he had inspired millions.

His story reminds us that the values he expressed were not empty words crafted for public admiration. He lived by them, even when doing so came at enormous personal cost. His belief that hope and conviction mattered more than material rewards became evident not only in the races he won, but also in the hardships he endured with remarkable dignity.

Distance running has changed dramatically since Zátopek's era. Today's elite athletes compete in a fully professional sport where prize money, sponsorship contracts, appearance fees, and endorsement deals can be worth millions. Success on the track and roads now offers opportunities that were unimaginable during the age of amateur competition. Professionalism has transformed the sport, allowing athletes to train full-time, access world-class coaching and sports science, and build financially secure careers.

Yet despite these changes, the essence of Zátopek's message has never lost its relevance.

Every elite runner naturally hopes to earn a good living from years of dedication and sacrifice. There is nothing wrong with financial success, and the rewards available today have elevated the standard of competition across the world. But history consistently shows that money alone is rarely enough to sustain greatness. The athletes whose careers endure the longest are often those driven by an inner passion to improve, to test their limits, and to chase excellence for its own sake. Financial rewards become the result of that commitment, not the reason for it.

When competition is motivated solely by wealth, its deeper purpose can fade. But when an athlete races with genuine belief, relentless determination, and an unwavering dream, extraordinary performances often follow naturally.

That is why Emil Zátopek's words continue to resonate across generations. His legacy extends far beyond Olympic medals and world records. It lives in every runner who laces up their shoes with a goal that cannot be measured in dollars, every athlete who refuses to surrender when the race becomes painful, and every competitor who understands that the greatest victories begin long before the finish line.

The economics of distance running may have evolved beyond recognition, but the heart of the sport remains unchanged. Every athlete still arrives at the starting line carrying something far more valuable than money—hope in their heart and dreams in their head. Those invisible qualities have always been, and will always remain, the true fuel of greatness.

Winning a major championship is never just about crossing the finish line first. Behind every gold medal lies a carefully crafted race plan, and Josh Kerr's unforgettable Commonwealth Games triumph in Glasgow was a perfect example of tactical brilliance meeting extraordinary finishing speed.

While the final time of 3:54.12 for the mile will be remembered as the official result, the split times reveal a much deeper story—one of patience, precision, and devastating acceleration when it mattered most.

Kerr resisted any temptation to force the pace from the gun. Instead, he settled into a controlled rhythm, allowing the opening stages to unfold naturally. His first four 100-metre segments—14.9, 15.1, 15.3 and 15.1 seconds—brought him through 400 metres in 60.4 seconds, a measured opening that conserved valuable energy while keeping him firmly in contention.

The second lap remained equally composed. Passing 500 metres in 15.3 seconds before recording splits of 15.7, 16.2 and 15.4, Kerr reached 800 metres in 2:03.0. The pace had eased, but that was exactly where the Scottish star wanted to be. Rather than chasing early speed, he was setting the stage for a decisive finish.

Everything changed after halfway.

Kerr gradually increased the tempo with smooth, controlled acceleration. His 900-metre and 1,000-metre splits of 15.2 and 14.9 seconds signalled that the race was beginning to stretch. He then surged through 1,100 metres in 14.3 seconds before covering the next 100 metres in just 13.4 seconds to reach 1,200 metres in 3:00.8.

From there, the home crowd witnessed championship running at its finest.

Instead of fading, Kerr became even stronger. He reeled off three consecutive 100-metre splits of 13.4, 13.4 and 12.8 seconds, dismantling the field with every stride. His final 100 metres were covered in a stunning 12.5 seconds, sealing an emphatic victory and sending the Glasgow crowd into celebration.

The progression of his race was remarkable. After opening with relaxed 15-second splits, Kerr transformed the closing stages into a demonstration of world-class speed endurance. His ability to accelerate continuously over the final 600 metres highlighted not only exceptional fitness but also supreme confidence in his race plan.

Championship middle-distance racing is rarely about producing the fastest possible time from the start. More often, it rewards athletes who understand when to conserve energy and when to unleash everything they have left. Kerr executed that philosophy to perfection.

His split chart paints the picture of a runner who never panicked, never wasted effort, and saved his greatest weapon for the closing stages. It was a textbook display of patience followed by relentless aggression—a combination that turned a tactical race into a memorable Commonwealth gold medal performance.

For aspiring middle-distance runners, Kerr's Glasgow masterpiece offers an important lesson: the strongest finish often belongs not to the athlete who runs hardest from the gun, but to the one who knows exactly when to make their move. On home soil, Josh Kerr timed that move to perfection, producing a performance that will stand as one of the defining moments of the championships.

At just nine years old, Oliver Smith has achieved something extraordinary—not by chasing records or medals, but by proving that determination, compassion, and consistency can create a life-changing impact.

Hailing from Wombwell, on the outskirts of Barnsley, Oliver set himself a remarkable challenge at the beginning of the year. Rather than attempting a single marathon, he decided to complete the equivalent distance of nine marathons over several months. From January 1 to April 26, the young runner covered an incredible 380 kilometres, breaking the distance into manageable daily runs suitable for a child his age.

His routine was built on dedication. Saturdays were reserved for parkrun events, Sundays for junior parkrun, while the remaining kilometres were steadily accumulated throughout the week. Averaging approximately 3.3 kilometres each day, Oliver never lost sight of the goal that inspired every step.

The challenge carried deep personal meaning. Last summer, Oliver's father, Tom Smith, suffered a devastating health setback after losing most of the vision in one eye. Medical examinations revealed a 4-centimetre meningioma wrapped around his optic nerve, leading to a complex 12-hour operation at the Royal Hallamshire Hospital in Sheffield.

Throughout the family's difficult journey, The Brain Tumour Charity provided invaluable guidance, support, and reassurance. Grateful for the help his family received, Oliver decided he wanted to give back in the most meaningful way he could. He launched a fundraising campaign with an initial goal of raising £2,000 to support others facing similar challenges.

What followed exceeded everyone's expectations.

Oliver brought his incredible fundraising challenge to a memorable conclusion at the Mini London Marathon, finishing on the very same day his mother, Hannah Smith, completed her first-ever London Marathon. It was a fitting family celebration of courage, resilience, and perseverance.

By the time Oliver crossed the finish line, donations had soared beyond £16,500—more than eight times his original target. His remarkable achievement captured the hearts of supporters, demonstrating how one young boy's determination could unite an entire community behind an important cause.

For Oliver, however, the journey is far from over. Inspired by the overwhelming support and the difference his efforts have made, he has already begun working toward his next fundraising challenge.

His story serves as a powerful reminder that age is no barrier to making a meaningful difference. Sometimes, the greatest acts of courage are measured not by speed or distance, but by the willingness to take one small step after another for the benefit of others.

Oliver Smith's inspiring journey is more than a fundraising success—it is a testament to the strength of family, the power of kindness, and the extraordinary impact that can begin with the simplest decision to help.

Sometimes the smallest opportunity creates the greatest triumph, and Jamaica's Navasky Anderson proved exactly that with a stunning performance to capture the men's 800m title at the 2026 Commonwealth Games in Glasgow.

Less than 24 hours after scraping into the final by the slimmest of margins, Anderson produced the race of his life, surging to victory in 1:45.33 to complete one of the most remarkable comeback stories of the championships. His gold medal was not only a reward for exceptional talent but also for courage, determination, and unwavering belief when everything was on the line.

The journey to the top nearly ended in the semifinals. Locked in an intense battle with England's Max Burgin for the final qualification place, Anderson threw himself across the finish line in a dramatic dive, stopping the clock at 1:45.38. That desperate effort earned him the last available place in the final as the fastest non-automatic qualifier, keeping his Commonwealth dream alive by the narrowest of margins.

With another chance in his hands, the Jamaican made sure it counted.

In a fiercely contested final, Anderson displayed outstanding tactical awareness and patience throughout the opening stages before unleashing a devastating finishing kick down the home straight. His perfectly timed acceleration left the rest of the field with no answer as he crossed the finish line first, securing a memorable Commonwealth crown and one of Jamaica's standout victories of the Games.

Australia's Luke Boyes delivered an impressive performance to claim the silver medal in 1:45.93, while Kenya's Wyclife Kinyamal battled strongly to take bronze in 1:46.12 after another highly competitive championship race.

Anderson's unforgettable triumph will be remembered as one of the defining moments of Glasgow 2026—a powerful reminder that championships are not always won by the fastest qualifier, but often by the athlete who refuses to surrender. From a fearless dive that kept his hopes alive to a brilliant gold-medal performance less than a day later, the Jamaican wrote one of the most inspiring chapters of these Commonwealth Games.

Men's 800m Final Results

1. Navasky Anderson (Jamaica) — 1:45.33

2. Luke Boyes (Australia) — 1:45.93

3. Wyclife Kinyamal (Kenya) — 1:46.12

Navasky Anderson arrived in the final as the last man to qualify, but he left Glasgow as the Commonwealth champion—a remarkable transformation that perfectly captures the unpredictable beauty of championship athletics.
