Three-time US Olympian Jenny Simpson has revealed that she will never compete in running again after surviving a sudden cardiac arrest that nearly claimed her life earlier this year.
The 39-year-old former middle-distance champion collapsed on June 16 while pacing a community mile event in Raleigh, North Carolina.
Simpson was helping a group of young runners during the Sir Walter Running Pop-Up Mile when she suddenly suffered cardiac arrest, bringing an extraordinary athletic career to an abrupt end.
Bystanders helped save the Olympian’s life
People at the event immediately intervened after Simpson collapsed, performing CPR and using an automated external defibrillator before emergency medical crews arrived.
The initial resuscitation was successful, but Simpson’s condition remained critical.
Her heart stopped functioning again after she reached hospital, forcing doctors to place her on life support.
She was subsequently transferred to Duke University Hospital, where specialists treated her for severe heart failure and the complications caused by fluid accumulating in her lungs.
Simpson recalls the moment her heart recovered
The former champion said her recovery took an unexpected turn after her condition appeared extremely serious.
She recalled that her heart eventually began functioning again, describing the development as miraculous.
Within days, Simpson said, her heart and lungs had recovered enough to function without mechanical assistance.
The athlete was eventually able to leave hospital and continue her recovery at home in Colorado.
Doctors diagnosed a rare heart condition
Simpson has now revealed that doctors diagnosed her with arrhythmogenic right ventricular cardiomyopathy, commonly known as ARVC.
The rare condition can affect the heart’s electrical system and cause scar tissue to develop within the heart muscle.
For an elite endurance athlete whose life has revolved around running, the diagnosis carries a particularly significant consequence.
Simpson said returning to running would now be dangerous.
A remarkable career has come to an unexpected end
Simpson’s decision effectively closes the book on one of the most decorated running careers in American athletics.
She became the 2011 world champion in the 1,500 metres and later won Olympic bronze in the event at the 2016 Games.
She also competed at three Olympic Games and built a career spanning distances from the mile through to the marathon.
Simpson officially retired from professional racing in 2024, but she remained involved in running and was still able to participate in community events before the cardiac arrest.
From world championship glory to fighting for her life
For Simpson, the contrast between her athletic achievements and her recent health crisis is stark.
During her career, she experienced the intensity of elite training, international competition and the pressure of performing on the world’s biggest stages.
She also stood on an Olympic podium and competed at major championships around the world.
Now, however, she has had to accept that competitive running can no longer form part of her future.
Simpson refuses to view the diagnosis as the end of her story
Despite losing the ability to run, Simpson has taken a positive approach to what lies ahead.
She described her future as a gift and said she remains hopeful that her life will continue to have purpose.
The Olympian acknowledged that the diagnosis has closed one chapter, but stressed that it has not brought her entire story to an end.
Her message reflects the perspective of an athlete who has spent years dealing with setbacks and challenges while continuing to compete at the highest level.
She asks supporters not to feel sorry for her
After breaking her silence on Instagram, Simpson made an unusual request of those sending messages of support.
She asked people not to tell her that they were sorry or that they felt bad for her.
Instead, she said she would prefer supporters to tell her that they are glad she survived.
For Simpson, simply being alive after the cardiac arrest has become the most important part of her story.
A second chance after a terrifying ordeal
The events of June 16 have left Simpson facing a radically different future, but her survival has given her a perspective that extends well beyond athletics.
She credits the immediate response of people at the track event, emergency treatment and her subsequent specialist care with helping her survive the ordeal.
Her recovery also means she can now focus on life away from competition while managing a condition that makes returning to her former training routine unsafe.
What’s next?
Simpson will continue her recovery at home in Colorado while adjusting to life with her diagnosis.
Although running is no longer considered safe for her, she has made it clear that she intends to approach the next phase of her life with optimism.
Her career as a professional runner may be over, but her influence on the sport and her experiences as an Olympian remain part of a remarkable legacy.
Summary
Three-time US Olympian Jenny Simpson has revealed that a rare heart condition has ended her ability to run after she survived a sudden cardiac arrest at a community track event in Raleigh.
Bystanders performed CPR and used a defibrillator before emergency responders arrived, while doctors later placed Simpson on life support after her heart stopped again at hospital.
After recovering, she was diagnosed with ARVC, making a return to running dangerous.
Rather than asking for sympathy, Simpson has urged supporters to celebrate the fact that she survived, saying she remains grateful for her extraordinary career and hopeful about the life ahead.
