American runner, Olympic and world champion
Three articles report the death of staff/fighters at Hyrox Bangkok and a notable runner's withdrawal after a cardiac event. The Bangkok Hyrox Open began Aug. 13 with 22,000 expected; one incident at the Queen Sirikit Center led to a fatal collapse, CPR, and hospitalisation. A separate case involves a US-based runner who has stopped competing after a cardiac arrest.
Olympic medallist Jenny Simpson has disclosed she has arrhythmogenic right ventricular cardiomyopathy (ARVC) after collapsing during a Raleigh, North Carolina event. She has asked fans not to offer pity, saying her story continues. The diagnosis means returning to running would be dangerous, and she will not pursue competitive racing in the future.
