Practicing different paces can provide the key to unlock your best performances. 

Most runners think pace is important because of PRs and faster race times, but paces have more significance than just those milestones. In fact even if your goal is to run longer distances or remain a runner for the rest of your life, it’s helpful to get to know your training paces. 

That’s why, according to run coaches, you will earn big rewards—both in terms of fitness and mental outlook—if you figure out how to calculate your paces when you run. 

“If you can run at the right pace, you’re going to run the right way and feel the right way,” Nike head running coach Chris Bennett tells Runner’s World. “And if you feel the right way, you’re going to want to do it again. That’s the most important thing.”

Whether you include speed workouts in your weekly schedule or only stick to zone 2 runs, you have an ideal pace range for almost every workout and distance you run. Let’s break down the various paces you should know and how to cue those up during various workouts.

The Benefits of Getting to Know Your Running Paces

Pace is measured in units of time per unit of distance, i.e., minutes per mile, and that pace will vary depending on the distance you’re running. For example, your fastest marathon pace will obviously be slower than your fastest 5K pace.

That’s why, when you use a run app or training plan, the program will suggest you do specific runs at a specific pace or even a variety of paces. For example, a speed workout may include short intervals at mile, 5K, or 10K paces.

Whether you train for 5Ks or marathons, or whether you run a few times a week with no particular distance in mind, running at the right pace for any given workout makes it more likely that you will better target physiological changes, such as boosting your VO2 max, Jeff Gaudette, founder of Runners Connect, tells Runner’s World. 

“Paying attention to your pace allows runners to properly hit the effort and outcome they’re targeting,” says Gaudette. “Newer runners, for example, will find that if they pay attention to pacing, they can run farther or finish runs not completely exhausted.” 

How to Calculate Your Paces

If You’ve Raced...

If your training plan or app suggests you use a specific pace during a run, how will you know what pace to use? Well, if you have some 5Ks or 10Ks under your belt, you can average your paces from those events and go from there.

This also works if you’ve run a marathon and a training plan calls for a long run at below marathon pace. 

You can also plug any race distance and your time into an online pacing tool, such as the Runner’s World training pace calculator, to find your ideal pace for various distances. 

But what if you haven’t raced or if you’re ready to race a new distance? 

If You Haven’t Raced...

A simple way to estimate your 5K and 10K paces is to do a mile time trial on your own, says Gaudette. “Races provide the best data point, but this is the next best thing,” he explains. “And the nice part of doing it this way is you can retest every few weeks. The more you do it, the more you’ll learn to pace yourself.”

To do a time trial, head to a track or an open road with a smartwatch or fitness app tracking your distance. Warm up for at least 10 minutes at an easy pace (you can easily hold a conversation as you run). Then “race” one mile. 

Gaudette advises running the first half at a difficult pace (think: you can barely speak a sentence) and then running the second half as fast as you can. This is your mile time. 

Now, plug that number into the Runner’s World training pace calculator, or simply add 40 seconds to your mile time to approximate your 5K pace and then about 60 seconds to get your 10K pace, says Gaudette. 

Other pace calculators will offer estimates for how long it might take you to complete different race distances. For example, if you plug one hour of run time and a distance of five miles into the Runner’s World pace calculator, you will get estimates like running 10 miles in 2 hours, a half marathon in 2:37, and a marathon in 5:14. 

Once you know your mile pace and the relative paces for longer distances, you can also play with the numbers in these online tools to see what your targeted paces need to be during training runs to hit different goals during races. 

Finally, you ca use the run/walk pace calculator to find out how to pace your intervals when using the run/walk method so you hit your goals.

How to Connect Your Paces to Your Effort

While paces are important, Bennett says you want to focus more on effort—or feel—during some of your runs, rather than numerical metrics every time you head out. That’s because several factors play a role in what exact pace is best for you on any given day and for any given workout, he explains. 

“Depending on where you are in your running journey or training cycle, what the weather is, what elevation you’re at, what you did yesterday, the numbers aren’t always the same,” says Bennett. “There’s some gray area on either side of what your 5K pace or effort should be. It’s dependent on a lot. That might seem overwhelming to a runner, but really, it should be the opposite. It gives you the freedom to step back and ask yourself: How does this feel?”

While it’s helpful to use your 5K and 10K paces as a baseline metric, Bennett believes runners benefit when they pay more attention to their effort level than specific numbers. To do this, represent your effort as a number, 1 through 10 (commonly referred to as your Rate of Perceived Exertion or RPE). For example, your 10K pace will feel like a 6 or 7 RPE, while your 5K pace will feel more like 7.5 or 8. 

To help runners dial in that effort even more personally, Bennett suggests using a couple words to describe what a pace feels like. Maybe your 10K effort feels strong and controlled, for example. Then, play on that description to dial into your 5K effort. You are kicking it up just a notch, so your 5K effort may feel fast and controlled.

“If you do this consistently and you keep a running log or keep metrics on your phone, after a couple weeks you can look back and find when I’m feeling good, this is roughly my pace on an easy run,” Bennett says. But then on stressful days, maybe that pace is a little slower and on days you’re well recovered, maybe it’s a little faster. 

How to Use Your Paces to Improve Your Runs and Races

“Every run has a purpose,” Bennett often says, and connecting the right pace to your effort level helps you find that purpose. For example, if you are trying to improve your overall half marathon race time, some of your training runs might include speed intervals that, over time, will help you become more efficient at running faster. That is, it won’t feel as hard to run fast.

With that in mind, it helps to understand the variety of runs there are on a training plan, because each of them requires a different effort and, therefore, pace. 

For example, easy runs are for going at a relaxed pace and building mileage; you should run them at a conversational effort and end feeling like you could keep going. Ideally, you’ll do these based on effort more than pace, but when you do check out your paces, you’ll likely find a big range, says Gaudette, and that’s okay.

In fact, your easy effort paces may change based on your mood and your energy level, among other variables. But if you notice that your easy pace is creeping up past your typical range, slow down. When you’re running faster than you should for any given outing, says Bennett, you’ll likely wind up stopping early and feeling defeated or even overtraining.

“It doesn’t matter if you’re brand new to running or if you’re heading to the Olympics, the majority of your running is easy runs,” says Bennett. “If you’re not nailing the easy runs, you’re not going to be nailing the harder stuff.”

As for “the harder stuff,” like speed workouts, pace can play a bigger role. Short intervals (think 400 meters) are designed to get you faster and allow you to practice running at paces above your goal race pace. You might clock these at your 5K pace or faster. Longer interval sessions, like mile repeats and tempo runs, help you improve your speed endurance, or holding onto a faster pace for longer. You might run these around 10K pace.

Over time, the combination of all these runs and mix of paces will improve your top speed, as well as your easy pace (while still feeling easy). That’s why it is so helpful to keep track of your paces with notes about your efforts and feelings about those efforts. Plus, it helps you notice and celebrate your progress.

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

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.

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.
