Strength training is an essential component of a well-rounded running training program, but for busy runners, it can be tricky to fit it into your program without jeopardizing your running workouts. Emma Vaillancourt, a registered physiotherapist and running coach in Thunder Bay, Ont., explains how to effectively incorporate strength training into your running routine to maximize gains and minimize burnout.

Should you strength train before or after running?

Vaillancourt explains that the order of strength training and running depends on your goals and where you’re at in your racing season. During the off-season, when running is less of a priority, you may choose to strength train first. In contrast, during the in-season, when your focus is on building running volume or intensity, running should usually come first.

If you plan to do strength training on days when you have intervals or speedwork, it’s generally better to do strength work after your run. This helps avoid fatigue and a possible negative impact on your workout. Vaillancourt also notes that running immediately before lifting can moderately impair lower-body strength gains. “If your goal is to improve strength, lift before the run,” she says. “If you aim to enhance endurance adaptations like aerobic capacity, the order doesn’t matter as much.”

Is it better to leave space sessions or can you do them back-to-back?

“It is recommended to allow at least three hours after high-intensity running before engaging in strength training,” says Vaillancourt. “During this recovery window, it’s important to refuel with a high-carb and protein meal to replenish your energy stores.”

Vaillancourt recommends at least 24 hours’ recovery after strength training before engaging in high-intensity running, but if you’re pairing strength training with easy runs, you can reduce the time between them.

Of course, most of us can’t plan our day around our strength training and running plans, so if scheduling becomes an issue, doing one activity right after the other is still beneficial. “Something is often better than nothing!” says Vaillancourt.  

Alternatively, she suggests splitting your strength training into smaller blocks, focusing on shorter, more frequent sessions throughout your week. This approach causes less fatigue and can be more manageable for some runners. “The idea here would be to do 10 to 20 minutes of strength work (maybe two or three exercises) but more frequently in your week, compared to the traditional 30 to 60 minutes done two or three times per week,” she says.

How often should runners strength train?

The frequency of strength training depends on several factors, including your experience level, the point in the season, and the time you can commit to training in a week.

In the off-season and early season, Vaillancourt recommends strength training two to three times a week, focusing on higher volumes of training. “If you’re training for a single race, such as a half-marathon or marathon, you will likely want to drop down to one to two times per week as your mileage peaks,” she says. “As you get closer to your race and are entering your taper, you can drop to once a week for maintenance.”

Running before or after workouts has a drastic effect on training effectiveness. Running before a strength workout can compromise strength training gains or cause injury. On the other hand, doing a strength workout before running could cause running form to deteriorate, which can also lead to injury or compromise strength training gains.

Athletes only have so much time. Sometimes that means doing cardio workouts (like running) and strength workouts (like lifting weights or bodyweight workouts) on the same day. Find out if it’s better to run before or after workouts and how to maximize same-day training benefits.

THE INTERFERENCE EFFECT

The interference effect is a physiological phenomenon that states that cardio or endurance exercise (like running and cycling) interferes with the cellular adaptions elicited via strength training (namely, muscle size and overall strength). However, it also states that strength training does not appear to necessarily adversely affect endurance adaptations.

The keyword here is: necessarily. More on that later on.

RUNNING BEFORE OR AFTER WORKOUTS DEPENDS ON WORKOUT GOALS

Athletes engaging in concurrent strength training and running need to prioritize goals. This should happen on an individual workout basis as well as overall athletic goals. For example, someone looking to build muscle mass and overall strength must concede that cardio training will–to some extent–inhibit strength gains. On the other hand, a runner is unlikely to be a very successful bodybuilder.

Athletes considering strength training and cardio training need to decide which is more important for their athletic development: muscle mass or endurance. This is not to say that strength-based athletes should stop all cardio. Likewise, endurance athletes like runners should do some strength training.

The careful blending of strength and endurance training is what is known as concurrent training. Strength training–such as with weights or bodyweight–is an important component of endurance performance. Sports like running and cycling do not stress all the necessary muscles in the body. For example, simply running or cycling can leave one with hip, lower back pain and upper body issues due to underdeveloped muscles. 

In short, most athletes should do a bit of strength training and a bit of cardio. The ideal blend of each will depend on the athlete’s goals: muscle mass or endurance.

RUN BEFORE OR AFTER WORKOUT AS A STRENGTH-FOCUSED ATHLETE

Athletes whose primary goal is to build muscle and overall strength should try to avoid doing cardio and strength training on the same day. If this cannot be avoided, strength-focused athletes should do their cardio workouts after strength training. This will help minimize the interference effect (i.e., the body will prioritize strength adaptations over endurance adaptations).

How long should cardio workouts take place after strength workouts? The longer the better. At least six to nine hours is ideal. Spacing strength and cardio workouts as far apart as possible will help maximize strength adaptations. Again, if pure strength is the primary goal, strongly consider doing cardio and strength workouts on entirely different days. Don’t do a hard strength workout and a hard (e.g., HIIT) running workout on the same day. 

ALTERNATING LOWER-BODY AND UPPER-BODY SAME DAY WORKOUTS

Cardio exercises like running and cycling are lower-body dominant. Performing upper-body workouts on the same day as running will have no meaningful effect on the strength workout. However, performing lower-body strength workouts shortly after a running workout will likely lead to diminished strength gains.

It follows that doing lower-body strength workouts should then only take place on non-running days.

Alternating workouts with upper-body strength days during running days and lower-body strength workouts on non-running days will help minimize or even eliminate the interference effect. The only caveat to this is if the athlete can handle the higher training load. This means having an optimized nutrition plan (here’s the 9 best foods for runners and the 9 best foods to build muscle), resting and being sensitive to their body’s injury or overtraining signals. 

RUNNING BEFORE OR AFTER WORKOUT AS A RUNNER

Strength training could be a key component to unlocking running performance. It may be the only way advanced runners can even achieve further progress. Beginner runners benefit from strength training by working muscles that help promote running economy and efficiency, which will ward off injury and promote total body fitness. 

If running (or any endurance activity, such as cycling) is a primary goal, do cardio after strength training. However, if the cardio session will be shorter and low intensity (like a simple endurance run of 30-90 minutes), doing high-repetition, low-weight or bodyweight strength training  AFTER running can help build muscular endurance and improve running stamina.

Muscular endurance is different than absolute strength. Whereas pure strength is about how much force one can produce quickly (e.g., during a squat), muscular endurance is about training muscles to resist fatigue over long periods of time. One can easily see how muscular endurance is beneficial to runners: running longer distances like half-marathons, marathons and even ultramarathons. Muscular endurance will allow runners to retain their running form longer, which means not only maintaining running economy for longer but also decreasing the risk of running-related injuries.

Sound worth it? Here’s how to do it:

Do an easy run. Try to avoid running hills. Don’t do intervals. Just do a basic endurance-paced run anywhere from 20 to 90 minutes. It should feel almost boring.

After the run and while the body is still warmed up, do a strength training session that focuses on high repetitions and low (if any) weight. Repetition ranges should be 20 to 30 per set. Cool down with light jogging.

Combining running and strength training back to back is a serious session. Make sure to fuel properly before, during and after (like with a hot cocoa recovery drink). Don’t finish the workout starving. The recovery demands from this type of training are huge–but so are the benefits. Don’t do these big sessions every day–twice a week is plenty and should likely be followed by a full recovery day or an easy run (for advanced athletes).

RUNNING BEFORE OR AFTER A WORKOUT IF THE GOAL IS TO LOSE WEIGHT

It is often recommended to do strength training before running to empty carbohydrate stores. The idea is to force the body to get its energy primarily from fat rather than carbs during the run. However, the problem with this strategy is that it is very difficult to finish a long-distance run on empty carbohydrate stores. While it is true that a much higher percentage of fat is burned for energy, the calorie burn, on the other hand, is relatively low because of the low intensity or low duration of the workout. 

On top of that, perceived exertion of the workout will be much greater when continuing to workout with depleted glycogen stores. This can cause athletes to prematurely quit the workout; therefore, reducing maximal calorie expenditure. Additionally, athletes who choose to work out this way will finish workouts extremely hungry. This can lead athletes to massively overeat after a very tough workout, which will likely result in weight gain and developing unhealthy nutrition habits.

If weight loss is a goal, a negative energy balance is key: If one burns more calories than they consume, they will lose weight. In the end, what matters is how many calories are burned in total through the workout. Spread your workouts out over several days. That way one can train at a high intensity and burn a lot of calories, and at the same time give the body the time it needs to recover properly before the next workout.

RUNNING BEFORE OR AFTER A WORKOUT IF THE GOAL IS TO IMPROVE OVERALL FITNESS

In this case, basically do cardio and strength training in whichever order. Still define a specific training goal for each session. Just be careful about doing too much and getting injured. Start slow, add a little bit of training each week, take a day off if aches and pains start to creep up. Once the gains stop coming, consider reexamining training structure to focus on more specific goals. Try this workout after a run for a great cardio and strength session.

This workout focuses on neglected leg muscles and glute strength (i.e., a firmer butt). It’ll also help improve posture. Learn and do the following movements: Curtsy lunge, kneel & stand, side lunges, single-leg deadlift and wall sits.

In general, avoid doing two workouts back-to-back. Spacing running and strength workouts far apart will allow the body sufficient time to adapt and recover before the next session. If running before or after a workout is the only option, follow the training schedule recommendations above to elicit maximal adaptations. If all of that is too complicated and the goal is to just get fit, do whatever is most convenient.

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.

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 Comrades Marathon Association has officially announced a detailed entry process for the 2027 race, which will unfold in three stages and give runners around the world the opportunity to secure their place in what promises to be one of the most significant editions ever held of The Ultimate Human Race.

The announcement followed the official launch of the 2027 Comrades Marathon on Wednesday, 19 August, when the centenary campaign, “The Greatest Story Ever Run,” was unveiled alongside a special logo created exclusively for the landmark 100th edition.

The launch also revealed several major highlights for the Centenary Race. The historic event will take place on Sunday, 13 June 2027, and will be a Down Run, with 28,000 places available. The entry process will include a ballot, while the race will offer a record R8.919 million in prize money. Organisers have also set an ambitious goal of raising R10 million for the Amabeadibeadi charities, adding an important charitable dimension to the centenary celebrations. One of the defining moments of the launch was the unveiling of the special Centenary mark, created to commemorate this extraordinary milestone in the history of the race.

The entry process begins on 25 August at 10:00 a.m. SAST, when entries open for Green Number runners, Yellow Number runners and Amabeadibeadi charity entrants.

The next phase follows on 2 September at 10:00 a.m. SAST, when entries open for Comrades Marathon Association members. This window will remain open for 72 hours or until the available entry allocation is filled, with places offered on a strictly first-come, first-served basis.

For general entrants, the process will move to a ballot system. General entries open on 9 September at 10:00 a.m. SAST, with runners able to enter the ballot until it closes on 22 September at 4:30 p.m. SAST. The ballot draw is then scheduled to take place on 23 September.

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.
