Running News Daily

Nearly 50 years ago I fell in love with running. I was far from a natural. When I was 8 years old, I was struck by an illness that left me with pneumonia in both lungs with one lung being collapsed. I survived that but was left with asthma that persists to this day. This was unfortunate as I loved sports. Asthma more or less disqualified me from participating in “running sports, " leaving me only with baseball as something I could do relatively comfortably.

In high school, I wanted to try wrestling. I figured that I could handle three 2-minute periods. However, I would soon learn that a lot of the training involved running and I struggled mightily to keep up with the other kids early in the season. The next season I hit upon the idea to ask our cross-country coach if I could train with that team, though not be part of the team. In this way, I could be conditioned before the start of wrestling season. And during wrestling season, I would show up two hours before the match to check my weight and run 2-4 miles before weigh-in. 

I graduated high school, but the running never stopped. I ran every weekend (4-10 miles each day) for decades. Running was so important to me that when setting up one of my company offices in Japan, I purposely chose a location in a place with a suitable place to run, near the Emperor’s Palace near Tokyo Station. The palace is surrounded by a circular (3km) moat that is a popular running destination. My ritual was that after a week of business, I would do four laps around the palace and then fly home to San Francisco.

Though I loved running I was never interested in racing until about age 50. In 2010, my new son-in-law invited me to join him in a 5K fun run in Lafayette. Passing all those 20-year-olds was all I needed to get the “bug.” I went on to run many dozens of races over the next years, mostly marathons, an ultra, and a triathlon. I was in the best shape of my life, rarely got sick, and was at the top of the world. That would change dramatically.

In 2013, I started noticing that on some days I would experience a strange fatigue that required me to take a walking break. I remember one day that I cut one of my runs short because I was disgusted with my performance. I kept my running clothes on and decided that I would try again later that day. That was the time I set a new PR for that training course. Something was not right, and these episodes of fatigue were increasing in frequency.

The last marathon I ran was in April 2016, a miserable affair clocking in a 4:53. By September, I couldn’t run a mile without a break. I complained to every doctor I met that “something was wrong”, but the standard response was that I was just getting older and I needed to lower my expectations. Even a cardiologist I had seen 10 years earlier told me that there was nothing wrong with me and even quipped “Guys like you are bad for business.” I wasn’t amused.

Finally, in 2019, my asthma doctor recommended a private practice cardiologist in Los Altos who might be willing to work with me. She spent two hours examining me, including an EKG and blood work. She found no problems but listened to my story about my newfound exercise intolerance. She said the only way to get to the bottom of it was to put me under a cardiac stress test.

I showed up at the hospital and they were ready for me. My doctor was there along with two technicians: one to operate the treadmill and monitor the EKG, and one with an echocardiogram scanner for a pre- and post-test scan of my heart. About 15 minutes into the test, about the same interval that I would experience fatigue during a run, the EKG technician exclaimed “Doctor!” and ran out of the room. The doctor told me to stop, asked me if I was OK, and asked me to lie down and have the other technician scan me.

The EKG technician quickly reappeared with defibrillating paddles and was stunned that I was calmly talking to the doctor. The cause of my fatigue was now clear– I was having a heart attack. A very deadly one at that, called Ventricular Tachycardia (VT) in which the top and bottom chambers beat at different rates causing your heart to stop pumping.

Now that the mystery was solved (I was not “fine”), we needed to identify the cause of this electrical misfiring. I was then directed to a cardiac electrophysiologist (EP) that specializes in this sort of disorder. He also took several hours to explain that there are nearly a dozen potential causes of this, and nearly all of them treatable. There was one (the least likely) however, that was not so easily treatable.

As it turns out, the least likely one Cardiac Sarcoidosis, was the one. This is a rare auto-immune disease that typically attacks the lungs but in even rarer cases can attack the heart. Lucky me. These “attacks” leave scar tissue on the heart that disrupts the normal electrical activity of the heart. My EP regretted telling me that this was out of his skill area and needed to refer me to Stanford where they have a cardiologist that specializes in this.

My experience at Stanford was great where a team of cardiologists took care of me. The first step was to see if the VT response to exercise was repeatable (it was). The second step was to confirm that sarcoidosis auto-immune cells were present in my body. The result of that test was positive. The cells were present, but the good news was that they were no longer in my heart and were “dormant.” But the damage was done. The final step was to install an implantable cardiac defibrillator (ICD) in my chest that has two wires screwed into the side of my heart. In case of a sustained VT episode, the ICD would automatically shock me back into rhythm.

My ICD was installed on February 12, 2020 shortly before the Covid lockdown. I cleared to begin running after about six weeks which I gleefully did after eight months of no running and four years of poor running. I am happy to report that I have had zero VT episodes, nor any other serious arrhythmias since the ICD was installed.

But my story is not quite over. Despite the lack of arrhythmias, my running performance has not returned to pre-sarcoidosis levels. I’ve worked with the Stanford cardiology team who have reiterated that my heart is working perfectly. With that ruled out, I asked for a referral to their pulmonary team to see whether there might be some lung function issues that are interfering with my return to normalcy. Like with my heart, I undertook a battery of tests looking for anything unusual.

The results of all these tests were that my lungs, despite a lifetime of asthma are working quite well. The penultimate step in this battery was a cardiopulmonary exercise test (CPET) that is most commonly used to test professional athletes. Despite my running complaints, the tests showed that my body was responding fairly well to exercise as I posted a 12.2 MET (Metaboloic Equivalent of Task).

I studied the voluminous data from the CPET and was struck by one thing– max heart rate. No, not the calculated 220-<age> that most runners are familiar with, but rather seeing that my heart rate levels off at 149 bpm and can go no higher no matter the stress. This is Father Time making his presence known. The reason I can no longer run as fast as I used to is because my heart can’t pump fast enough to generate the required oxygen to propel my body at those speeds. It's basic physics, so simple. 

I decided to investigate this briefly and look at some representative races to see if I could see this in actual race data. I looked at the data from the California International Marathonfrom 2022 curious to see an age-related pattern. During my short racing career, I would typically place in the top 20% of my age bracket. I extracted data for Mens Masters into a chart to show Max HR vs. the top finisher and the top 20% finisher. This has given me some consolation that the slowdown is natural and will continue.

One more thing I’d like to share, especially with older runners. Since the ICD, I have found it hard to rebuild my aerobic base. I’ve concluded that the reason for this is that I was still trying to train like when I was a teenager back when my Max HR was 200! Somewhere in my memory banks, I recalled something about low heart rate training and quickly found the MAF methodby Dr. Phil Maffetone. In a nutshell, Maffetone advises training at ultra-low heart rates (180-<age>) to develop a core aerobic base. The process can take 3-6 months and involves running at an agonizingly slow pace (at first.) I am happy to report that this is the one thing that is working for me and for the first time in a long time I am again running with joy.

This has been a very personal story but one that I thought I should share with our running community. I feel that running may have saved my life. If I hadn’t challenged my doctors that I was not “fine” the worst could have happened. We runners know our bodies better than anyone and when something doesn’t feel right, it’s probably not. Don’t be afraid to aggressively advocate for yourself. Your life might depend on it.

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.
