These mysterious bumps can cause discomfort and pain, but prevention and early treatment can help you stick to your training schedule.

Picture this: You’re blissfully clocking your miles on a Saturday morning until you feel a small but growing pressure on top of your foot. It’s slight, so you ignore it, but over time that discomfort starts to become more noticeable—and once you take your running shoes off at home, you notice a bulb-like bump on your foot.

What gives? You could have what’s known as a ganglion cyst. These sometimes painful bumps aren’t often talked about in the running community, but they’re one of the most common soft tissue masses found in the foot and ankle, per a 2023 review in the Journal of Clinical Orthopaedics and Trauma. Plus, they can derail your training if not addressed.

Here’s everything you need to know about ganglion cysts as a runner, including how to prevent and treat them. 

How might a ganglion cyst show up in runners?

A ganglion cyst develops slowly over weeks or months, but it may grab your attention during a run. 

“There will be some soreness associated with a ganglion during a run due to shoe pressure against it,” says Karen A. Langone, D.P.M., a Southampton, New York-based spokesperson for the American Podiatric Medical Association and podiatrist who specializes in sports and fitness medicine. “You might notice a lump on the foot, which can worsen during the run.” 

That lump on your foot can be easy to confuse with a number of other conditions. Found along a tendon or near a tendon, a ganglion cyst can be mistaken for an exostosis, for example, which is a benign (noncancerous) bone tumor, per the Cleveland Clinic. 

“It might also be confused with a stress fracture of a metatarsal bone,” says Alex Kor, D.P.M., a spokesperson for the American Podiatric Medical Association, a podiatrist at Hendricks Regional Health in Danville, Indiana and team podiatrist for the athletic programs at Butler University. A metatarsal stress fracture is a break in the bone from repeated injury or stress, which can be caused by running. 

What is a ganglion cyst?

On the other hand, ganglion cysts are noncancerous bumps that usually appear along your tendons or the joints of the wrists or hands, but they can also occur in ankles and feet, according to the Mayo Clinic. They’re filled with a jellylike fluid. 

“A ganglion cyst, like any mass, makes the runner’s foot feel tight,” says Kor. “The pain can be characterized as dull or sharp if mileage is extended or there is increased shoe pressure.” 

This cyst is usually caused by a bony point that’s exacerbated by shoe pressure (and possibly by your foot swelling at the end of a run), a tendon that gets overused (which may be the result of tendonitis), or from acute trauma. The fluid in the tendon sheath can “leak out” after overuse or trauma to form the ganglion cyst, adds Kor.

Once one of these things occurs, the inflammation within the tendon sheath accumulates in one area and worsens, forming the ganglion cyst. 

Although they’re filled with fluid, they can feel firm to the touch, per Yale Medicine. They can be as small as a pea or as large as an inch in diameter. Sometimes, they can affect joint movement and cause pain if they press against a nerve. 

The majority of ganglion cysts occur on the top of the foot or the front of your ankle, says Kor. They are rare on the bottom of the foot.

Risk factors for these cysts include sex and age (most often, ganglion cysts occur in women between the ages of 20 and 40) and osteoarthritis (particularly when they occur in the hands), per the Mayo Clinic. 

Should you run with a cyst?

You can continue to run with a ganglion cyst, especially if there is no pain. Even if there is some pain, your level of discomfort will determine the best steps for treatment.

“This is not a condition that will significantly worsen [if you run on it],” says Kor. “In other words, it is not like a stress fracture that can ‘break’ to the point that surgery is needed.” 

However, it’s important to check with a doctor to make sure the bump is a ganglion cyst and not something more serious, and to determine ways to avoid discomfort.

Being a runner alone does not increase your risk of ganglion cysts, but your foot shape may play a role. “They are a little more common in very high arched feet and very flat feet,” says Kor.

How can runners treat ganglion cysts?

First, visit your doctor, who may conduct imaging tests like an X-ray and ultrasound to confirm that it is a ganglion cyst (and not something else). 

Once the bump has been identified as a ganglion cyst, there are a few treatment options, starting with these less invasive methods:

Padding

This can be placed around (not on) the ganglion cyst to avoid pressure from a running shoe. “A pad or blister bandage directly over the ganglion cyst may worsen the pain,” says Kor. “Typically, a horseshoe pad or donut pad is applied to offload the cyst.”

Icing

You can also ice your foot after a run and on a daily basis for 20 to 30 minutes. Place a towel between your foot and the ice pack to avoid skin irritation. “Ice can cause vasoconstriction to reduce inflammation, swelling, and pain,” says Kor. 

Changing Shoes

A supportive shoe has the potential to reduce overuse, which may help in the initial stages of a ganglion cyst, says Kor. A supportive shoe should not bend at the sole (typically, this has nothing to do with the brand name or price of the shoe).

Taking Breaks from Footwear

When you’re not running, avoid shoes that exacerbate the ganglion cyst area. For instance, skip the one-strap sandal that directly rubs the cyst area. Unsupportive footwear, like flip-flops with a flexible sole, can also worsen the cyst. 

Adjusting Your Shoe Laces

If the ganglion is on the top of the foot, your shoelace pattern can be changed to avoid direct pressure on the ganglion. For instance, your podiatrist might recommend a lacing pattern often used for patients with high instep (the bony structure on top of your foot). 

In this case, cross your laces as usual toward the bottom of the tongue, skip crossing them over in the middle (and instead create a line along each side of the tongue), then finish lacing near the top of the tongue. This offloads the top of the foot that may be affected by the cyst. See an example of how to do it here. 

Take Anti-Inflammatory Medication

If approved by your doctor, you can take over-the-counter anti-inflammatory medications to ease the discomfort of a ganglion cyst.

If you’re in pain, it’s worth speaking with your doctor about longer-term solutions for treating the cysts. Kor notes that many runners may see little to no improvement with these conservative options. 

If these steps don’t help, your podiatrist might suggest an in-office procedure in which the fluid is withdrawn and sometimes injected with a small amount of cortisone to shrink the remaining cyst—or complete surgical removal of the cyst.

Even surgery isn’t a magic bullet: The recurrence of ganglion cysts after surgical removal ranges from 4 to 40 percent, according to a 2021 study in The Archives of Bone and Joint Surgery. 

Clearly, it’s important to speak with your doctor transparently about your pain levels to determine the pros and cons of each treatment. Fifty percent of the time, ganglion cysts resolve on their own, according to a historic study in Current Reviews in Musculoskeletal Medicine. 

How can runners prevent ganglion cysts?

Some of the methods described above for treating an early-stage cyst can also be used to prevent one in the first place, starting with your running shoe.

“Ganglions are often found over areas where the bone is prominent and there is aggravation from shoe pressure,” says Langone. “A well-fitting running shoe is an important part of avoiding ganglions, as is altering lacing patterns to avoid painful pressure.”

If your doctor has already aspirated your ganglion cyst and you want to prevent recurrence, a well-fitting shoe and altering lacing patterns may still help—along with icing after runs. 

“Over-the-counter or custom-made orthotics can also indirectly help with a ganglion cyst,” says Kor. “There is some indication that increasing support within the shoe can reduce the overuse on a tendon, which may in turn reduce the irritation that contributes to a cyst.” 

Your podiatrist can prescribe custom orthotics based on your foot’s specific shape. That said, if a ganglion cyst is already significantly symptomatic, an over-the-counter orthotic will typically not help.

As with most things, prevention and early detection are key. If you start to notice discomfort or an unusual bump, make an appointment with your doctor to discuss treatment options—so you can get back to pain-free miles.

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.
