What started as a routine community track night in Raleigh turned suddenly serious on Tuesday when Olympian Jenny Simpson, 39, collapsed while pacing a mile group at a Pop Up Miles meet. Bystanders and emergency medical responders administered CPR after she briefly had no pulse, and Simpson regained a pulse before being transported to a nearby hospital for treatment. Her current condition has not been publicly disclosed.
According to TMZ, the medical emergency unfolded during the weekly Pop Up Miles session and drew an immediate response from fellow runners and EMS. The outlet reports that Simpson "needed CPR to restart her heart" and was rushed to a local hospital after a pulse was restored. TMZ also noted that race organizers shared a brief statement on social media following the incident.
Race organizers wrote that "Jenny is receiving excellent medical care, and our thoughts are with her and her family during this time," according to the reporting. Their message also asked the community to keep Simpson and her family in their prayers. Hospital officials have not released a detailed medical update.
At a Pop Up Miles Meet-up
Pop Up Miles is a recurring mile series run by Sir Walter Running that features paced mile heats and community track sessions around the Raleigh area. As described by Sir Walter Running, the series is intended as an inclusive weekly chance for runners of many speeds to race a timed mile on the track. The low-key events typically pull in local clubs, volunteer pacers and recreational runners tuning up for races during the season, more focused on splits than on sirens.
Simpson's Track Résumé
Simpson is a retired American middle- and long-distance runner who represented the United States at the 2008, 2012 and 2016 Olympics, earning a bronze medal in the 1500 meters at the Rio 2016 Games. She also won the 1500m world title in 2011 and has been a central figure in U.S. middle-distance running for more than a decade. Her career accomplishments and background are outlined on her athlete profile.
Why Bystander CPR Likely Mattered
Medical experts have long stressed that immediate bystander CPR and early defibrillation are critical in sudden cardiac arrest. The American Heart Association notes that prompt CPR can double or triple a person's chance of survival, and that every minute without CPR or defibrillation significantly reduces those odds. In out-of-hospital cardiac arrests, especially when someone collapses in front of witnesses, quick action from nearby responders often becomes the difference-maker - which helps explain why early reports about Simpson emphasize the response from fellow runners and EMS.
What Comes Next
Officials have released only limited information so far, and no detailed public medical bulletin has come from local hospitals. For now, the running community is waiting and watching, and this story remains in progress. This report will be updated if verifiable statements from medical providers or Simpson's representatives become available.
