Adequate nutrition can be easier said than done. Here’s how to up your intake.

As you ramp up run training in prep for marathon season, you may assume your appetite will follow a similar upward trajectory. But that’s not always the case. 

On the contrary: Intense or prolonged exercise can actually suppress hunger, quashing your desire to eat, Jordan Hill, RD, a Colorado-based registered dietitian and certified specialist in sports dietetics with Top Nutrition Coaching, tells Runner’s World. 

Combine that with other factors—including lack of awareness about what and how much your body needs to sustain training, not having enough time to meal prep, and fear of weight gain—and it’s no surprise that many endurance runners are under-fueled.

Research confirms the struggle: A 2021 study of 207 cross-country runners, for example, found that 79.5 percent of female athletes and and 54 percent of male athletes were at risk of low energy availability (not intaking enough calories to support their workouts and daily needs). 

That’s a problem, since subpar nutrition can trigger a cascade of issues that negatively affect your workouts—and overall health. 

Here, with the help of two registered dietitians, we explain why eating enough calories is crucial to both your run performance and day-to-day functioning, telltale signs you’re underfueling, and easy ways to rev your appetite to help meet your caloric needs. 

Why Adequate Calorie Intake is So Crucial for Runners

Calories are synonymous with energy, Hill explains, so not getting enough calories means you’re not getting enough energy for your body. That deficit can influence pretty much every bodily function including your immune system and metabolism, heart, hormones, GI system, and even mental health, she explains.

More specifically, not getting enough calories can decrease your performance in workouts, lead to excessive fatigue, increased your risk for injury and illness, cause nutritional deficiencies, decrease muscle mass, trigger hormonal imbalances, and cause negative psychological effects, such as mood swings, difficulty concentrating, and increased stress levels, says Hill. In other words, when you don’t fuel enough your body and mind take a serious hit.

Additionally, if you continually eat less than your body needs, you risk suppressing your appetite overall, Amity Lui, MS, RD, a New York City-based sports dietitian who works with runners, tells Runner’s World. “Not eating enough will actually impact your body’s metabolic rate and cause your body to kick into survival mode,” she adds. This means your body will require less calories over time and will shut down certain functions to save energy while increasing storage of body fat, according to Lui. 

In some cases, underfueling can lead to relative energy deficiency in sport (RED-S) syndrome–essentially, a chronic state of low energy availability, Lui explains. Unfortunately, RED-S can cause long-lasting, negative effects, including decreased bone density, chronic fatigue, poor recovery, and diminished enjoyment of running since “you literally have no energy for it,” says Lui.

On the flip side, amping up calorie intake to meet your needs “will reap almost immediate benefits,” says Lui. These include increased energy, mood, cognition, and run performance, she says. You’ll also benefit from enhanced recovery, a strengthened immune system, improved body composition and cardiovascular health, elevated psychological well being, reduced risk for nutritional deficiencies, and improved hormonal balance, says Hill.

Signs of Underfueling

There are a number of signs you’re not eating enough to support your training, and tuning into them can help you rev up your nutrition habits before longer-term problems arise. “If athletes cue into how they’re feeling and what their body is doing, they can usually pick up on not eating enough before RED-S would become an issue,” says Hill. 

Common signs of underfueling, according to Lui and Hill, include:

Decreased energy levels and feelings of abnormal fatigue—think: needing long naps every day, going to bed earlier than usual, or saying no to plans because of fatigue

Decreased performance in workouts—this could include being unable to complete your workouts, or consistently not reaching your target paces

Psychological and emotional changes—examples: mood swings, slowed cognition, irritability, lack of concentration, and generally feeling unmotivated

Prolonged muscle soreness and slow recovery

Getting sick or injured more often

Unintentional weight loss or difficulty maintaining your current weight

Hormonal disruptions, including loss of menstrual cycle

Changes in sleep patterns

Always feeling cold

Hair loss

12 Ways to Increase Appetite

A big reason runners struggle to get in all the calories they need is they simply don’t feel hungry. 

Now, there are a “bunch of ways that our body tells us we’re hungry,” says Hill. You may not always hear your stomach growl, but could instead experience hunger in the form of a headache or fatigue. “It’s important for each person to figure out what’s their individual cue for hunger to help them be aware of that,” says Hill. 

With that in mind, here are 12 expert-backed ways to kickstart your appetite and thus up your chances of eating enough calories. 

1. Eat breakfast

A lot of Lui’s clients report having just coffee as their breakfast, and that’s a no-no. Skipping meals can lead to prolonged hunger, which can suppress your appetite in the long-term. “It’s almost like ignoring your body’s hunger cues,” Lui explains. “If you keep ignoring something, your body will no longer register it as a sign that you need food.” 

Additionally, forgoing the first meal of the day may make it more difficult to achieve your overall calorie totals for the day. Plus, dodging a.m. fuel is associated with nutrient deficiencies and poor diet quality, according to other research. 

Not sure what to chow on? Check out these on-the-go breakfast ideas for runners, plan your breakfast in advance with some meal prepping, or whip up one of these recipes to fuel your morning runs. 

2. Consume smaller, more frequent meals

Instead of cramming all your calories into three big meals—which can be daunting if you’re just not feeling hungry—opt for smaller, more frequent feeding sessions. There’s no perfect cadence, but as a general rule of thumb, aim to nosh every two to three hours, suggests Hill. “It doesn’t have to be full-on meals,” she warns. Nutrient-dense snacks can fit the bill, too (more on that below). 

3. Reach for easy-to-digest fuel post workout

The most common time Hill sees athletes struggle with low appetite is right after a training session, since, like we mentioned, prolonged or intense training can suppress hunger. But getting fuel in anyways—ideally within 30 minutes of a workout—is an important part of the recovery process and can, in many cases, help kickstart your appetite, says Hill. 

Postrun, she recommends reaching for refreshing, easily digestible snacks, like a fruit smoothie, because they’ll be easier to stomach—literally. Lui, for her part, is a big fan of recovery shakes that have a three-to-one ratio of carbs to protein for optimal refueling. 

4. Opt for energy-dense bites

If you’re really struggling to feel hungry, but know it’s time to intake calories, pick higher-calorie, higher-nutrient snacks to maximize the fuel you’re consuming, says Hill. So instead of having just a plate of crackers, have crackers with cheese and deli meat or nut butter, she says. Or in lieu of popcorn alone, combine popcorn with jerky or popcorn and nuts. Other options include Greek yogurt with granola, fruit, chia, or flax seeds; toast with nut butter; or hummus and veggies. The goal, says Hill, is to pair more than one macronutrient together. 

5. Stay hydrated

Dehydration can screw with your appetite, says Hill, so it’s important to stay on top of your intake. Hydration needs vary and depend on factors including how much you exercise and sweat, your overall health, and the heat, humidity, and elevation of your environment, per the Mayo Clinic. As a general rule of thumb, you’re probably adequately hydrated if you don’t feel thirsty and your pee is light yellow or colorless.

6. Consider liquid calories

When hunger just isn’t there, it’s often easier to drink versus chew your calories. That’s where things like smoothies, shakes, juices, and soups can be helpful. “It is less taxing to sip on something versus having to prepare, reheat the food, cook it, and then chew it,” says Lui. To make your sippable meals as nutritious as possible, consider adding nutrient-dense extras like nut butters and seeds, she says. 

7. Find foods you actually enjoy

This may sound like a no-brainer but finding foods you actually enjoy eating—and not focusing so much on what you feel like you should be eating—can help combat a suppressed appetite, says Lui. After all, you’re much more likely to want to nibble when it’s something you genuinely like versus something you feel obligated to choke down. 

8. Reduce fiber intake

High-fiber foods can help keep you ~regular~ but they also keep you feeling full for longer, which may not be desired when you’re struggling with appetite. Fiber-rich meals, like large salads, “can result in bloating and delay gastric emptying, both of which can make you feel less hungry,” explains Lui. So, instead of opting for a kale salad at lunch, consider a grain bowl with quinoa, farro, rice, or barely; in lieu of a whole baked potato at dinner, have a bowl of pasta. 

9. Keep mealtime exciting

Hill explains it this way: “If you’re eating the same thing over and over, you’re already going to be disinterested, and then you throw no appetite on top of that, and it’s really going to make you not want to eat.” 

Beat the mealtime blahs by trying new-to-you flavors and textures. Make a reservation at that just-opened restaurant in town. Or, explore food blogs, watch cooking shows, and follow social media accounts that offer diverse and innovative recipes, suggests Hill. 

10. Pack snacks

To help with eating consistently, carry non-perishable snacks with you—like granola bars or trail mix—so that you’ll have something to nosh on during those times when you’re commuting and transportation gets held up or you end up having to run an extra errand. “I like to call them emergency snacks, even though sometimes I eat them not in an emergency,” says Lui. 

11. Cook with oils

Don’t be afraid to cook with oils, says Lui. This will allow you to get more calories in without having to eat a higher volume of grub. Plus, the fats in the oil enhance the absorption of fat-soluble vitamins, including vitamins A, D, E, and K, Lui adds. So instead of boiling or steaming your veggies, for example, coat them in oil and grill, stir fry, air fry, or sauté them. 

12. Tap an expert for help

Because dietary needs and the factors affecting your appetite can be so individualized, it never hurts to consult a registered sports dietitian for personalized advice. They can help you figure out where you can incorporate more nutrient- and energy-dense meals and snacks into your day, says Lui, as well as determine how you can best fuel for your training goals. 

British middle-distance star Keely Hodgkinson is proving that the impact of an Olympic champion extends far beyond the medals she wins, as her remarkable achievements continue to inspire young girls to believe in their own sporting dreams.

A heartwarming image of a young British girl recreating Hodgkinson’s iconic champion pose, dressed in a replica of her racing kit and proudly draped in the Union Jack, has captured the beautiful connection between sporting heroes and the next generation of athletes. It is a powerful reminder that what begins as admiration for a champion can eventually become the inspiration to follow in her footsteps.

Hodgkinson secured her place among Britain's greatest middle-distance runners at the Paris 2024 Olympic Games, where she won the women's 800 metres gold medal in 1:56.72. The victory marked the culmination of years of determination and perseverance, bringing Olympic glory to a career that had already seen her claim silver at the Tokyo 2020 Olympics and the 2022 World Athletics Championships.

Her triumph in Paris was more than a personal milestone. It was a moment that allowed countless young athletes to see what was possible through dedication, confidence and a willingness to pursue ambitious goals.

For Hodgkinson, the power of inspiration is something she understands personally. As a nine-year-old girl, she watched Dame Jessica Ennis-Hill win heptathlon gold at the London 2012 Olympic Games. That unforgettable performance helped spark her own interest in athletics, setting her on a journey that would eventually lead her to the top of the Olympic podium.

Now, more than a decade later, Hodgkinson has become the very kind of sporting role model who can ignite that same ambition in another young athlete.

The young fan's recreation of her Olympic hero is a touching reflection of how sporting success can influence children long before they take their first competitive steps on the track. Wearing a champion's colours, adopting her winning pose and celebrating her achievements may seem like simple gestures, but they represent something much bigger: the beginning of a dream.

Hodgkinson has also developed a distinctive identity beyond her performances, with her confident race-day style, Union Jack-inspired details and unapologetic personality making her a recognisable figure in British athletics. For many young fans, she represents a modern champion who combines world-class ability with individuality and self-belief.

Her story also highlights the importance of visibility in sport. When young girls see women achieving extraordinary things on the world's biggest stages, they are given tangible examples of what determination and ambition can accomplish. Champions such as Hodgkinson help make athletics more accessible and exciting, encouraging the next generation to lace up their trainers, join a club and discover their own potential.

Of course, not every young admirer will become an Olympic medallist, but the influence of a sporting hero can extend well beyond competition. The confidence to try something new, the discipline to work towards a goal and the courage to keep going after disappointment are lessons that can shape a lifetime.

For Hodgkinson, her legacy will ultimately be measured by more than the gold medals she wins or the records she may break. It will also be reflected in the young athletes who find the courage to chase their ambitions because they watched her succeed.

Just as Ennis-Hill's triumph at London 2012 helped inspire a young Hodgkinson, the British 800m champion is now passing that inspiration forward, showing a new generation that today's dreams can become tomorrow's achievements.

Somewhere among the young fans proudly recreating her winning pose could be a future British champion, an Olympic medallist or even the next athlete to redefine the limits of the 800 metres.

Today, she may be a little girl looking up to her hero. Tomorrow, she could be the champion inspiring millions of others.

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.
