These are the common causes of back pain in runners, according to experts.

If you want to solve a problem, you have to go to the source. The only problem: Pinpointing the source of your back pain can be somewhat tricky. The discomfort can stem from your running, but also activities beyond your workouts, like lifting something that’s too heavy or sleeping on a brand new mattress. 

To help find the common causes of back pain in runners, though, researchers of a study published in Pain Research and Management surveyed 800 marathon runners to better understand how they experience lower back pain and identify potential risk factors. Of the marathoners who reported pain, risk factors included an insufficient warmup, fatigue, poor running posture, and even the environmental temperature. 

While these may cause you to experience aches in your back, we asked a physical therapist and sports physician for other surprising and common causes of back pain—plus what you can do to avoid all of these risk factors for discomfort.

1. You’re Not Strength Training

A weak core—or any weakness along your kinetic chain, including in the muscles around your feet, ankles, knees, or hips—can affect your body’s ability to absorb the impact of running. 

“If a runner’s body isn’t absorbing shock well or efficiently, there will be excess impact forces that are transmitted through the legs and up into the spine or lower back, which can cause low back pain or discomfort,” Daniel Giordano, D.P.T., C.S.C.S., physical therapist and cofounder of Bespoke Treatments, tells Runner’s World. 

This is why it’s so important to strength train at least twice a week, so you can build stronger running muscles for the road. For runners with a weak core or hips, practicing planks and lunges can help stabilize these muscles, says Giordano. Other moves to target typically weak areas of runners include single-leg calf raises for stronger ankles, lateral banded walks for knee strength, and glute bridges for stronger hips. 

Muscle weakness can also cause runners to overcompensate in other areas of the body, which can result in poor running form and also contribute to back pain, Giordano adds. For example, a weak core can cause a runner to slouch or lean forward which places extra stress on the low back and can disrupt running mechanics. 

The best way to zero in on weaknesses and compensations is to visit a professional, like a physical therapist, sports physician, or orthopedist, who can use technology like a 3D gait analysis to assess your running form and measure your ability to absorb shock, and motion analysis to measure your joint range of motion, says Giordano. 

2. You Don’t Warmup

You need to warmup before every workout to properly prepare your muscles for what’s to come, especially if you spend a lot of time sitting throughout the day.

“If you’re sitting all day, your hips are probably going to be tight,” says Giordano. “Then, if you’re not warming up after sitting and just going straight into a run, you’re not going to be ready to run.” Essentially, your body won’t be able to get through ideal gait mechanics without overcompensating. 

For example, “tight hips can limit your range of motion and force other parts of your body, such as your back, to compensate for the restricted movement, which can also result in pain and discomfort,” he explains. 

To fix this, Giordano suggests doing a dynamic warmup, which requires actively stretching your hips, glutes, hamstrings, quads, calves, and rotating your spine to ensure your muscles are ready to go at run time. To target these areas and activate these muscle groups, try bodyweight squats, mini band lunges, pogo jumps, and standing spinal rotations. Also, jog in place or walk for a few minutes before you start picking up the pace, he adds.

3. You’re Wearing the Wrong Shoes

Finding the right pair of running shoes will help improve shock absorption, which can decrease back pain. 

When determining which shoes to choose, it’s all about your running gait, Aaron Mares, M.D., associate professor at the University of Pittsburgh Medical Center and associate medical director for the Pittsburgh Marathon tells Runner’s World. You may need more or less cushion depending on your biomechanics. 

More specifically, your level of pronation—the inward movement of your foot as it rolls optimally to distribute the force impact as you run—will contribute to the kind of running shoe you need, says Mares. 

A running gait analysis can also help identify the shoe that’s best for you. For example, if the analysis determines you overpronate, you might want to consider insoles or a stability shoe. 

Also, look for a lightweight shoe with cushion, as this can not only help you avoid pain but also keep you from slowing down, says Giordano. Heading to your local running store to test shoes before you buy them is always a smart move. 

4. You Increase Your Mileage Too Quickly

“If you’re increasing your volume or your intensity too fast, and your body’s not equipped to handle it, that will lead to excessive force on your lower back,” says Giordano.

That’s why it’s important for you to slowly increase your training volume by 10 to 15 percent each week, so your body can build strength and endurance, he explains. This means if your longest run is five miles but your goal is to run 10 miles, you’d increase your longest run by about 0.5 miles each week until you reach your goal. 

Also, you may want to consider where you’re running, especially if you frequently run on concrete or up hills, as this can also contribute to your pain. “If you’re running on a really hard surface, you’re going to put a lot more impact force up through your kinetic chain versus if you run on soft dirt, fine gravel, or a trail,” says Mares. 

A change of scenery can offer a simple fix—head out to the trails or softer paths like grass—but you also might want to consider dialing back your frequency or intensity. Cross-training with cycling or swimming, especially if running somewhere else isn’t an option, is also a smart option for sidestepping aches when your back asks for it, Mares adds. 

5. You're Not Recovering Properly

“If you’re not sleeping well and not recovering, your body’s never healing. You're constantly in a state of stress, and probably should take more days off,” says Giordano.

Your body needs complete rest days mixed into your schedule so it can properly heal before your next workout. Adequate rest days will prevent you from overtraining, therefore helping you decrease your chances for muscle issues, like back pain, that can stem from an overuse injury.

Ideally, you want to have one full rest day a week, and get at least seven to nine hours of sleep each night.

6. You’re Not Drinking Enough Water

Believe it or not, inadequate hydration levels can also contribute to the risk of back pain. “If you’re not well hydrated, your muscles can become tight and it can lead to strains or sprains, including those in your lower back,” says Giordano.

To avoid this, aim for the Institute of Medicine’s recommendation of men taking in at least 3.7 liters (or 125 ounces) and women 2.7 liters (or 91 ounces), per day, from fluids and water-containing foods.

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.

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.
