Here’s what experts say about the causes of that uncomfortable, tingling sensation and how to cope with it.

As a runner, you try to prepare for everything: You have a waterproof jacket for that 60 percent chance of rain, anti-blister socks, and a supply of gel packs for Saturday long runs. However, something that you may be less prepared for is relentless itching and tingling.

Known as “runner’s itch,” this sensation makes hitting the road uncomfortable for many runners, especially those just starting out or getting back into a running routine. 

“Runner’s itch wasn’t something that was particularly researched and documented before the 1950s, but it’s been consistently described in literature in some way since about the 70s,” says Braden Romer, Ph.D., an associate professor of exercise science at High Point University in High Point, North Carolina. “We’ve seen the prevalence go up as there are more individuals taking part in physical activity. I run into it quite often when dealing with athletes.” 

If you want to run more but can’t stand the urge to stop and scratch, here’s what to know about runner’s itch and how to soothe it.

What causes runner’s itch?

The causes of runner’s itch may range from minor inconveniences to more serious health conditions. Although more research is needed to fully understand what triggers this sensation, here are five potential causes. 

1. Dry or Irritated Skin

Both humidity and dryness in the air can lead to runner’s itch. 

“If you sweat a lot or if it’s very humid or raining, and your clothes get wet, you run the risk of skin irritation or itchiness,” says Melissa Kendter, C.P.T., a Philadelphia-based United Endurance Sports Coaching Academy (UESCA) running coach. 

Meanwhile, another common cause is dry air and dry skin. Friction from running can exacerbate this and cause unpleasant itching.

“Some research has suggested hydration is a factor as well,” says Romer. “If you’re not drinking enough water, your skin gets dry and itches. When you begin to workout, especially with workout clothes, that may trigger an effect as well.”

Running can also exacerbate eczema, a group of inflammatory skin conditions that lead to issues like itchiness and dry skin. 

“If you’re prone to eczema, exercise might make it worse,” says Minneapolis-based William Roberts, M.D. chief medical officer of the American College of Sports Medicine and former director of the sports medicine program at the University of Minnesota Medical School. “If you notice a skin rash, talk to your doctor.”

2. Histamine Release

A predominant theory behind runner’s itch is a histamine release at the onset of exercise, says Romer. Aerobic or endurance exercise can generate a localized anaphylactic reaction within the exercised muscle tissue, which causes histamine release, per a 2017 study in Exercise and Sport Sciences Reviews. 

“There’s some research to suggest that the itching may be related to histamine release at the onset of exercise, particularly in high-intensity exercise,” Romer explains. “If somebody hasn’t been working out or running, or they haven’t warmed up and jump right into a high-intensity workout, that may be triggering a greater histamine release from within the muscle cells.”

This histamine release, in turn, could cause that uncomfortable and itchy feeling. 

2. Blood Vessel Expansion

When you run, blood flow increases to your tissues, causing vasodilation (the widening of blood vessels). One theory is that the increased size of your capillaries causes an itching sensation.

“The capillaries start to expand, which may send a triggering response to some of the nerve fibers around that area,” says Romer. You may be more prone to this if you haven’t run for a while or are just starting out.

“This typically can happen for newer runners or ones getting back into the routine of running, because their bodies aren’t adept at this process,” says Kendter. “If your fitness routine has been put on the back burner for some time, you have a higher risk.”

However, this theory does have its skeptics. Romer adds that there are multiple pathways that have been proposed for runner’s itch and the symptom is not well understood. This was evident even in the differing opinions among the experts we spoke to—Roberts, for instance, has doubts that vasodilation could cause itching.

The bottom line: Though runner’s itch could potentially be related to blood flow, more research is needed to fully understand the mechanisms behind this process.

4. Exercise-Induced Urticaria

In more rare cases, allergic responses to exercise can cause severe symptoms. Exercise-induced urticaria is a rare clinical condition that causes flushing, itchiness, and hives after a workout, per a March 2022 single case study in Cureus. A minority of patients can even develop anaphylaxis, which is a severe, life-threatening allergic reaction. 

“Exercise-induced anaphylaxis can cause a fast heart rate and potentially the swelling of the throat and blocking of the airways,” says Roberts.

About 30 to 50 percent of exercise-induced anaphylaxis is food dependent, meaning it only occurs with the combination of a specific food and exercise, per another single case study, published in 2017 in Canadian Family Physician. 

Many different types of food have been found to have a triggering effect, including wheat, shellfish, nuts, tomatoes, peanuts, fish, pork, beef, mushrooms, hazelnuts, eggs, peaches, apples, milk, and alcohol.

If you suspect you’re experiencing urticaria, it’s important to see your physician to start a treatment program. This could include taking antihistamines before you run and carrying an EpiPen with you. If you do experience allergic reactions, it’s best to run with a buddy who knows how to help if you have a reaction. 

People with severe cases of exercise-induced urticaria may need to avoid certain types of exercise and foods (or, rarely, exercise altogether). 

5. Cholinergic Urticaria

Another condition that could be the cause of itching is cholinergic urticaria, which is characterized by itching and/or a stinging pain, redness, and bumps. 

Think of this as a heat-triggered reaction: Symptoms develop after an increased body temperature has been stimulated repeatedly, such as through exercise, per a 2023 review in the American Journal of Clinical Dermatology.

“This is also pretty rare,” says Roberts. “It’s a response to the skin warming that occurs with running.” 

Cholinergic urticaria is often associated with serious symptoms like anaphylaxis and severe pain. This condition comes on very quickly and may also involve an antihistamine treatment plan. Your doctor may conduct testing to confirm that you’re experiencing cholinergic urticaria, which may involve raising the body temperature through exercise on a treadmill or stationary bike. 

Who’s most prone to runner’s itch?

When it comes to everyday runner’s itch that’s not related to a more serious medical condition like exercise-induced urticaria or cholinergic urticaria, runners who are just starting out or who haven’t exercised in a while may be more likely to experience it. 

“I’ve seen this with athletes who have taken time off,” says Romer. “My wife also struggles with runner’s itch quite a bit. If she takes some time off from high-intensity runs for a bit, especially in the winter, it really gets after her for the first few workouts.” 

If the itching is due to dry skin, factors like age, climate (think desert-like climates with low humidity or cold climates with heavy wind), genetics, or health conditions like eczema or diabetes can play a role, per the Cleveland Clinic. You may also experience more dry, itchy skin during the winter or if you’re not drinking enough water. 

How can you sooth runner’s itch?

For many people, runner’s itch will fade away with regular exercise, unless it’s a symptom of a more serious condition. “It generally subsides relatively quickly after several workout sessions or modifying hydration intake,” says Romer. 

You can also aim to soothe runner’s itch by properly easing into your run.“Do a good warmup so your body has a gradual increase in temperature and the blood gets flowing to the muscles in advance, rather than a rapid increase,” says Kendter.

Try to keep running throughout the year: Although the first couple of weeks may feel uncomfortable, if you stay consistent and allow your body to adapt to your routine, you’re less likely to experience the itch. 

Staying properly hydrated and using a moisturizer to soothe dry skin can also help. Roberts recommends moisturizing creams like Vanicream, which is available over the counter. 

All of this said, talk to your doctor if runner’s itch continues for you or if symptoms are severe—say, it’s accompanied by rash or hives, is extremely painful, or continues/worsens over time.

“If it becomes a chronic response, where you’re not seeing a diminished response even if you’ve been able to regularly exercise, see a physician,” says Romer. 

The prospect of seeing one of athletics' biggest stars back on the track is growing stronger, with Jakob Ingebrigtsen reportedly targeting a return to competition later this summer following his recovery from Achilles tendon surgery.

According to comments made by his agent, Daniel Wessfeldt, in an interview with Norwegian media, the double Olympic champion could make his long-awaited comeback at one of three major European meetings in July. The leading options under consideration are the Monaco Diamond League on July 10, the Hungarian Athletics Grand Prix on July 14, and the London Diamond League on July 18.

For athletics fans, the possibility of Ingebrigtsen lining up in London would add another layer of excitement to an already highly anticipated Diamond League meeting. The Norwegian middle-distance sensation has become one of the sport's most dominant figures in recent years, collecting Olympic, world and European titles while consistently rewriting record books.

His 2026 campaign was put on hold after he underwent surgery on his Achilles tendon earlier this year, forcing him to focus on rehabilitation rather than competition. Since then, questions have surrounded when the 24-year-old would be ready to return to racing.

The latest update suggests that decision will largely depend on how his training progresses over the coming weeks. If recovery continues according to plan, July could mark the beginning of his return to elite competition ahead of the latter stages of the season.

A comeback at either Monaco, Budapest or London would immediately place Ingebrigtsen back among the sport's biggest storylines. Each meeting is renowned for producing world-class performances, and any appearance by the Norwegian would attract significant attention from fans eager to see how quickly he can regain top form after his injury setback.

While no final decision has been confirmed, the signs are increasingly positive. After months away from competition, Jakob Ingebrigtsen appears to be edging closer to a return, with London's Diamond League meeting emerging as one of the most intriguing possibilities on his road back to the track.

Should his recovery continue smoothly, athletics could soon welcome back one of its brightest and most influential stars.

What should have been the defining moment of Emad Bashir-Mohammed's young running career instead turned into one of the most talked-about controversies in American road racing this year.

The 23-year-old crossed the finish line first in the men's citizen's race at the prestigious Bolder Boulder 10K on Memorial Day in Colorado, stopping the clock at an impressive 29:50. His performance was not only a commanding victory but also one of the fastest winning times ever recorded in the event's long and celebrated history. Bashir-Mohammed finished eight seconds clear of his nearest challenger and appeared to have secured a breakthrough triumph.

For nearly two hours, he was the undisputed winner.

Then everything changed.

Race officials announced that Bashir-Mohammed had been disqualified after determining that he had started in the wrong wave. According to Bolder Boulder regulations, he had been assigned to the AA wave but lined up with the faster A wave, which began earlier. Event rules allow runners to move backward into a slower wave, but prohibit athletes from advancing into a faster one.

As a result, Bashir-Mohammed's victory was erased from the record books.

The citizen's title was subsequently awarded to Nickolas Scudder, who crossed the line second in 29:58. The promotion handed Scudder back-to-back citizen's race victories, while Bashir-Mohammed was left to grapple with the disappointment of losing a win he believed he had earned on the road.

The disqualification has since ignited widespread debate across the running community.

Bashir-Mohammed maintains that he did not intentionally violate the rules. He claims that after collecting his AA bib, he spoke with race personnel and was permitted to start with the A wave after presenting evidence of his recent performances. In a statement shared after the race, he expressed frustration over the decision, arguing that his goal was simply to compete against the strongest field available and produce the fastest time possible.

Race organizers, however, stood firmly behind their ruling. Officials stated that wave-assignment regulations are clearly communicated in pre-race information and reiterated during packet collection. They also noted that hundreds of participants are disqualified each year for moving into faster start groups, emphasizing that consistent enforcement is necessary to maintain fairness for all competitors.

The incident has divided opinion among runners and fans alike. Some believe the rules must be applied equally regardless of an athlete's finishing position, arguing that wave assignments are a fundamental part of race organization. Others feel the punishment is harsh, particularly if Bashir-Mohammed genuinely received approval to move up before the start.

What remains undisputed is the quality of his performance. On the roads of Boulder, Bashir-Mohammed demonstrated the fitness and speed required to outrun the field by a significant margin. Yet in road racing, crossing the finish line first is only part of the equation. Compliance with race regulations carries equal weight.

For Bashir-Mohammed, the day will be remembered as a painful lesson in the fine margins that can define elite competition. A remarkable run delivered a memorable victory, but a dispute over wave placement ultimately overshadowed the achievement, leaving behind a controversy that continues to fuel discussion throughout the running world.

A fast race, a costly administrative error, and a debate that may linger long after the finish-line tape has been packed away.

Audrey Werro announced her arrival as one of the early stars of the 2026 outdoor season with a commanding victory in the women’s 800 metres at the Rabat Diamond League, producing a performance that exceeded even her own expectations.

The Swiss middle-distance talent surged to victory in a brilliant 1:56.56, breaking the meeting record and delivering one of the fastest times recorded worldwide this season. In a race packed with quality, Werro displayed exceptional composure, confidence, and finishing strength to separate herself from the field and stamp her authority on the event.

What made the performance even more remarkable was the athlete's surprise at the level she had already reached so early in the campaign.

"I was not expecting such a strong start to the season," Werro admitted after the race.

The race unfolded at a relentless pace, but Werro remained perfectly positioned throughout. As the athletes approached the bell lap, she glanced at the clock and immediately sensed something special was within reach.

"When I saw the time at the bell, I felt really confident," she said. "I'm really happy with the Meeting Record and looking forward to the rest of the season."

Her confidence proved justified. Maintaining her rhythm over the final 400 metres, Werro powered down the home straight to secure the victory and rewrite the Rabat meeting record books in the process.

The performance sends an early warning to her rivals ahead of a season that promises major championships and high-profile Diamond League battles. Beyond the record-breaking time, Werro's display highlighted her growing maturity as a racer, combining tactical awareness with impressive speed and endurance.

With the outdoor season only beginning, the 1:56.56 clocking suggests that even faster times could be on the horizon. If Rabat is any indication, Audrey Werro may be poised for the biggest season of her career.

Her emphatic victory in Morocco was more than just another Diamond League win—it was a statement of intent from an athlete determined to challenge the world's best throughout 2026.

The city of Boston is set to welcome back one of its most celebrated champions as Kenya’s Sharon Lokedi headlines a world-class field for the 2026 B.A.A. 10K presented by Mass General Brigham Cancer Institute on June 21.

Fresh from another remarkable victory at the Boston Marathon in April, Lokedi returns to the streets of Boston and Cambridge carrying both momentum and confidence as she aims to defend the title she captured in dominant fashion last year.

The two-time Boston Marathon champion has developed a special connection with the historic race city. In 2025, she produced a course-record performance of 2:17:22 to win the Boston Marathon before returning this year to claim another victory in 2:18:51, the second-fastest winning time in the event’s storied history. Her success has cemented her status as one of the premier road runners in the world.

Lokedi will be making her first competitive appearance since her marathon triumph and arrives as the reigning B.A.A. 10K champion after clocking 31:39 over the challenging 6.2-mile course in 2025.

“Boston has become a very special place for me,” Lokedi said ahead of the race. “The atmosphere created by the fans and the community is unlike anywhere else. I’m excited to return and give everything I have to defend my title.”

The women’s race promises to be highly competitive. American Olympian Rachel Smith, who finished second at the Boston 5K in April, leads the domestic challenge. Kenya’s strong contingent includes African 10,000m champion Gladys Kwamboka, former B.A.A. 10K runner-up Stacy Ndiwa, and experienced road racer Viola Cheptoo. British Olympian Jessica Warner-Judd adds further international depth to a field packed with proven performers.

The men’s race is equally impressive, featuring elite athletes from 13 nations.

Ethiopia’s Dawit Seare enters as one of the leading contenders after capturing the 2025 Boston 5K title and bringing the fastest 10K personal best in the field at 27:21. Kenya will be represented by an accomplished group led by Alexander Mutiso, winner of the 2024 London Marathon and runner-up at last year’s New York City Marathon.

Patrick Kiprop also arrives in outstanding form after securing victory at the prestigious BolderBoulder 10K on Memorial Day, while Alex Masai returns looking to continue his strong record in Boston. Masai recently finished ninth at the Boston Marathon and has earned three top-ten finishes at the B.A.A. 10K.

Among the international stars making their mark is South Africa’s Adriaan Wildschutt, who makes his race debut after an impressive season highlighted by victory at the NYC Half Marathon in 59:30. Ethiopia’s Olympic bronze medallist Hagos Gebrhiwet adds further quality to the field, bringing a wealth of championship experience and previous success in Boston.

Canadian national 10K champion Andrew Alexander, two-time U.S. Olympian Hillary Bor, marathon standout Ryan Ford, and reigning USA 25K champion Andrew Colley complete a field stacked with talent and depth.

With defending champions, Olympic finalists, national champions and rising stars all converging on Boston, the 2026 B.A.A. 10K is shaping up to be one of the most competitive editions in recent memory. For Sharon Lokedi, however, the mission is simple: return to the city where she has repeatedly excelled and add another memorable chapter to her growing Boston legacy.
