Expert advice for focusing on your best event to maximize your running potential.Ever notice that some runs and races are more satisfying than others? These workouts aren’t necessarily the easiest runs or even the ones that are the most fun. Instead, they’re fulfilling because the distance feels challenging, but doable. You collect your medal and walk away thinking, “I bet I can do even better next time,” rather than, “thank goodness that’s over.”

If you have already clicked with a specific distance, you may have already found your running “sweet spot,” or the race length that fires up your inner athlete and gets you training for your next PR. But if you’re new to running or haven’t yet hit your racing stride, some experimentation and a little self-reflection will help you determine where to focus your time and effort when registering and training for events. To help you land on your sweet spot (and figure out what to do when you get there), we chatted with a few run coaches who have worked with athletes of all levels of experience and race preferences. Here’s what you need to know. 

What factors determine your sweet spot race distance?

Before you declare yourself a 10K devotee or commit to running a marathon in every state, give yourself adequate time to build a personal relationship with running and experience different races. 

“I don’t know if there’s really a set amount of time required to figure this out,” Matt Forsman, USATF/RRCA-certified running coach and race organizer at Sasquatch Racing, tells Runner’s World. “Some people run for years before determining what distance is their sweet spot. For others, a certain distance immediately speaks to them. If you’re new to running, I’d say give yourself at least six to nine months to build some running fitness, try a few distances, and go from there.”

As you rack up the miles and try different races on for size, it can be helpful to keep these factors in mind: 

Fitness and Experience

“Your current level of running fitness should be an important part of the calculus in determining what race distance is best for you,” Forsman says, noting that shorter distances like 5K and 10K, while they present their own unique challenges, are generally more beginner-friendly than half marathons and marathons. 

You may find that, even as a newbie, these shorter distances enable you to make noticeable progress that’s reflected in your race times. These wins are valuable, as they can keep you engaged and motivated. 

Schedule and Lifestyle

Anyone who’s trained for a marathon or ultramarathon will tell you how all-consuming it can be. Some people have the necessary bandwidth or a flexible schedule. Others have the support and resources to fit training between competing priorities, like work, family obligations, and social events. But if you simply don’t have the time and energy to train for a specific distance, it’s probably not your sweet spot.“You should fit running in and around your life and not life in and around your running,” Todd Buckingham, Ph.D. exercise physiologist at PTSportsPRO in Grand Rapids, Michigan tells Runner’s World. “We do this because it’s fun. We do this because we want to push ourselves. But hopefully not to the extent of alienating friends and family. You need to find a distance that will work with your life.” 

Location

If you train outdoors, you will always contend with temperature, climate, and terrain. Therefore, where you live will likely play a role in determining your sweet spot, Will Baldwin, USATF and VDOT-certified running coach in Flagstaff, Arizona tells Runner’s World

“If summer temperatures soar, focusing on local 5Ks instead of marathon training will be much more manageable,” Baldwin says. Of course, you can beat the heat by logging miles before or after sunrise, running on a treadmill, but workarounds often require extra planning and schedule adjustments. The same goes for training in frigid, icy temps.

In some cases, your zip code may present an advantage, as year-long temperate weather and extended daylight hours open up more opportunities for longer outdoor training runs. 

“And if there’s a fantastic trail system nearby with plenty of races, it’s the perfect chance to test those trail-running skills and have some fun with it,” Baldwin adds.

Past Performance

Your race history is a clue to where your natural talents lie, which can help inform your sweet spot. “Genetics do play a role,” Buckingham says. “Some people have the diesel engine where they can just go all day long, but they can’t go any faster…other people are really good at short distances but struggle at long distances.” Buckingham and Baldwin recommend checking out online tools like the VDOT Running Calculator, which uses one race distance time to determine your estimated time for other distances. Runner’s World also has an easy-to-use race time predictor. Say, for example, your half-marathon PR is 2:10. The calculator uses this information to suggest an exhaustive list of predicted race times, including a 58:40 10K. However, if your 10K PR is actually 56:10, you may be better suited to the 10K. 

“Athletes can use this tool to see which of their PRs is the most distinguished for each distance, helping them determine their ideal race distance,” Baldwin says. 

You can also garner a lot of information by participating in local races and looking at race results. “See where you finish in relation to other people your age and sex because that will probably tell you just as well,” Buckingham says. 

Injuries

“I think it's important to consider any aggravations and injuries you’ve incurred,” Forsman says. “Running is a high-impact sport that generates about three to seven times your bodyweight in impact force per foot strike. If you have [had] a number of injuries in your recent or distant past, shorter distances like the 5K or 10K may make the most sense. Conversely, if you’ve never had any running-related injuries and your running fitness level is high, a longer distance might work great for you.”

Your Happiness and Enjoyment

Do you notice that some races are simply more fun than others? Pay attention to those gut-level feelings, even if they contradict all of the other data you’ve collected, Baldwin says. 

“When figuring out an athlete’s ideal race distance or their sweet spot, I love to start with what excites them the most,” he says. “Even if someone shines in a 10K or half marathon, their heart might be set on the full marathon. Passion is often the fuel source of consistent training, so tapping into that excitement is really important.”How do you level up in your sweet spot race distance?

Once you find your sweet spot, you may need to make some adjustments to your running routine because a training program should be tailored to your upcoming event, if you plan to race.

“If you’re currently running a few easy miles a few times a week but really want to run a fast 5K, you’re going to need to inject some ‘quality,’ like tempo, intervals, and hills, to develop strength and speed,” Forsman says. “If you want to simply tackle a longer distance like a half or full marathon, you’re going to need to gradually add some more miles into your training to build stamina and endurance.”

Focusing on one distance also allows you to fine-tune your fueling and hydration strategy, especially if you opt for longer distances. “If the event we’re training for is going to take us over 90 minutes to complete, we have to start talking about and practicing fueling. We’ll need to incorporate either some liquid fuel or energy gels to help us finish the race and utilize all of our fitness,” Baldwin says. “It’s an added expense to have fuel for all of the important long runs and races, so it’s also something to consider when choosing your ideal race distance,” he adds. 

Are there downsides to sticking with one race distance?

It can be rewarding to climb the ranks in sweet spot events, but the experts caution against getting too “stuck” in your sweet spot. 

“You should definitely be mixing up the types of races you do,” Baldwin says. “It’s common for a marathon runner to come to me who has been stuck at a certain level for years. When I go back through their training history, they almost always have been doing only marathons for several years in a row. They’ve neglected the shorter races, speed work, and their leg turnover.” Baldwin explains that training at different paces engages different energy systems, and temporarily focusing on shorter, faster distances can improve your speed and efficiency, even on slower endurance runs. 

The same concept applies to runners with a shorter sweet spot. “If shorter distances like the 5K or 10K are your thing, there’s still utility in tackling longer distances. Training for a longer distance can help you better manage fatigue in the latter stages of your 5K or 10K,” Forsman says. 

Plus, you could miss out on what got you hooked on running in the first place. “Professional athletes have to specialize and really just focus on one event because that’s how they earn their livelihood. But the average runner should have fun with it,” Buckingham says. “If you have fun doing one race distance, that’s fine. But don’t be afraid to jump in the local 5K if your friends ask you to join them.”  

Ethiopia’s Fotyеn Tesfay Haylu delivered one of the most remarkable women’s half-marathon performances ever seen on American soil on Sunday, powering to a commanding victory at the 2026 Buenos Aires Half Marathon in Argentina in 1:03:57.

Running with exceptional confidence and strength, Tesfay took control of the race and produced a superb solo performance to rewrite the event record. Her breathtaking run also carried historic significance, as she became the first woman to break the 64-minute barrier for the half marathon in the Americas, producing what is being celebrated as the fastest women’s half-marathon performance ever recorded on the continent.

The Ethiopian star was in a class of her own, crossing the finish line more than a minute clear of Turkey’s Nevin Can, who finished second in 1:05:06. Another Turkish athlete, Selin Can, completed the podium in third place with 1:05:11, as the leading trio all produced strong performances on the fast streets of Buenos Aires.

Kenya also featured prominently in the top positions, with Irene Jepchumba Kimais taking fourth in 1:06:04, followed by Sheila Chepkirui in fifth with 1:06:13. Magaret Akidor Ngathike finished sixth in 1:06:46, while fellow Kenyan Deborah Samum claimed seventh place in 1:08:32.

Brazil’s Nubia de Oliveira Silva was eighth in 1:11:13, while Argentina’s Sofia Luna and Dahyana Juarez rounded out the top 10 with times of 1:11:21 and 1:11:28, respectively.

Top 10 Women – 2026 Buenos Aires Half Marathon

1. Fotyеn Tesfay Haylu (Ethiopia) – 1:03:57

2. Nevin Can (Turkey) – 1:05:06

3. Selin Can (Turkey) – 1:05:11

4. Irene Jepchumba Kimais (Kenya) – 1:06:04

5. Sheila Chepkirui (Kenya) – 1:06:13

6. Magaret Akidor Ngathike (Kenya) – 1:06:46

7. Deborah Samum (Kenya) – 1:08:32

8. Nubia de Oliveira Silva (Brazil) – 1:11:13

9. Sofia Luna (Argentina) – 1:11:21

10. Dahyana Juarez (Argentina) – 1:11:28

For Tesfay, it was far more than a race victory. Her 1:03:57 performance was a statement of extraordinary quality, combining speed, endurance and remarkable solo running to produce a landmark result in Buenos Aires. In a race that will be remembered for years to come, the Ethiopian did not simply win—she redefined what was thought possible for women’s half-marathon running in the Americas.

Ethiopia’s Yomif Kejelcha produced one of the most extraordinary performances in road racing history on the streets of Buenos Aires, Argentina, reclaiming the half marathon world record with a sensational 56:51 performance at the 2026 Buenos Aires Half Marathon.

The former world record-holder delivered a breathtaking exhibition of speed and endurance to take 29 seconds off the previous pending mark of 57:20, set by Uganda’s Jacob Kiplimo and takes a huge chunk from his own former official world record. Kejelcha's new performance is pending the standard ratification procedures, but if officially ratified, it will return the world record to the Ethiopian star and mark another remarkable chapter in the evolution of the event. 

Kejelcha's achievement is particularly significant because the 57-minute barrier had already been broken before. Jacob Kiplimo had previously run under 57 minutes, clocking 56:42 that was not ratified demonstrating that the once-unthinkable barrier was possible. Kejelcha, however, has become the second man to run under 57-minute barrier who now returns to the top of the all-time rankings with another historic performance in Buenos Aires.

The Ethiopian's race was remarkable not only for the final time but also for the way he built his performance. He covered the opening five kilometres in 13:44 before reaching 10km in 27:18. Rather than slowing, Kejelcha accelerated through the middle stages, passing 15km in 40:39 and 20km in 54:02 as he continued to push the limits of elite road racing.

By the time he reached the finish line, Kejelcha had completed the race at an extraordinary average pace of approximately 2:42 per kilometre, producing one of the most astonishing sustained efforts ever witnessed in distance running. His stunning run sent a powerful message to the athletics world and further strengthened his status as one of the most formidable distance runners of his generation.

Behind the record-breaking champion, Ethiopia completed a dominant clean sweep of the men's podium. Tadese Worku Gebresilase claimed second place in 59:18, while Bereket Nega Batebo secured third in 1:00:17, giving Ethiopia a memorable one-two-three finish in the Argentine capital.

Kenya’s Jonathan Kipkoech Kamosong finished fourth in 1:00:20, followed by compatriot Simon Maywa in fifth with 1:00:55. Argentina’s Ignacio Erario gave the home supporters plenty to celebrate with an impressive sixth-place finish in 1:00:57, breaking the one-hour barrier in front of an enthusiastic local crowd.

Dillon Kipyeko of Kenya finished seventh in 1:01:07, with Robert Kiprop Koech eighth in 1:02:01. Mexico’s Julio Ortiz Ponce took ninth place in 1:03:17, while Colombia’s Jimmy Gómez completed the top 10 in 1:03:34.

The Buenos Aires Half Marathon will now take its place in the history books as the scene of a truly extraordinary breakthrough. For Kejelcha, this was more than just another victory. It was a spectacular return to the top, reclaiming a world record he had previously held and once again rewriting the limits of the half marathon.

The 56:51 performance remains pending ratification, but Yomif Kejelcha's run has already delivered one of the defining moments in the history of road racing.

Kenya delivered another commanding display of distance-running excellence at the Antrim Coast Half Marathon, with Isaia Lasoi leading a memorable Kenyan clean sweep of the men's podium in a race packed with world-class performances.

Lasoi emerged victorious after a thrilling battle at the front, crossing the finish line in a superb 58:26 setting a new course record. His winning performance underlined his strength and speed over the half-marathon distance, but he was made to work all the way by fellow Kenyan Daniel Mateiko, who finished just three seconds behind in 58:29 after an electrifying duel for the title.

The contest between the two leaders produced one of the standout moments of the race, with both athletes pushing deep into elite territory as they fought for victory. In the end, Lasoi found just enough to secure the win, while Mateiko's narrow defeat highlighted the remarkable depth and quality of Kenya's leading distance runners.

Vincent Kipkorir completed the Kenyan sweep, taking third place in 1:00:38 to ensure that all three places on the podium belonged to Kenyan athletes. Samwel Chebolei added further Kenyan strength to the results, finishing fourth in 1:01:01, while Amos Langat was also among the leading finishers.

The international field featured several prominent names. Australia's Jimmy Whelan produced a strong run, while Ethiopia's Yismaw Dillu featured among the front group. American marathon star Galen Rupp also delivered a notable performance, clocking 1:01:29 in another competitive outing for the experienced distance runner. Former world-class track and road athlete Edward Cheserek was also among the top finishers.

Lasoi's 58:26 victory, however, was the defining performance of the day. Together with Mateiko and Kipkorir, he gave Kenya a perfect podium and another emphatic reminder of the country's extraordinary strength in elite road running.

The Antrim Coast Half Marathon once again provided a fast, competitive stage for some of the world's finest distance runners, but when the decisive moments arrived, it was Kenya that owned the podium.

One of the most iconic milestones in the history of ultramarathon running is drawing closer, with entries for the historic 100th edition of the Comrades Marathon set to open on Tuesday, 25 August 2026.

The Greatest Story Ever Run is preparing for its most historic chapter yet.

American sprint standout Sam Blaskowski is taking steps toward an international future with Poland after uncovering a powerful connection to his family's ancestral homeland.

The 23-year-old sprinter, who has established himself as one of the fastest Americans of his generation with a personal best of 9.89 seconds in the 100 metres, has begun the process of obtaining Polish citizenship with the aim of eventually representing Poland in international competition.

Blaskowski's connection to the country traces back through his great-grandparents, Franciszek and Julian Błaszkowski, who emigrated from Poland to the United States in 1905. Their journey more than a century ago has now opened an unexpected new chapter for their descendant, whose athletic ambitions could soon carry the Błaszkowski name back onto the international stage under Polish colours.

The sprinter has already received support from the Polish Athletics Association as he works through the citizenship and eligibility process. Should his transfer of allegiance be completed, Blaskowski could become a significant addition to Poland's sprint programme.

His credentials certainly make the prospect an exciting one. In addition to his sub-10-second speed over 100 metres, Blaskowski owns a personal best of 19.93 seconds in the 200 metres, demonstrating the kind of versatility that could prove valuable both individually and in Poland's 4x100m relay squad.

For Blaskowski, however, the move is about more than simply changing national colours. It represents an opportunity to reconnect with his family's heritage while pursuing his ambitions at the highest level of the sport.

With his sights set on becoming part of Poland's international sprint team and competing for relay medals, Blaskowski's journey from discovering his Polish roots to potentially representing the country of his ancestors could become one of the most fascinating allegiance stories in world athletics.

A century after Franciszek and Julian Błaszkowski left Poland for America, their family's story may now be coming full circle—this time at full sprint.
