Elaine Stypula, a 60-year-old ultrarunner from Detroit, was found dead on the course Friday morning, approximately 10 kilometres from the start of the Hardrock 100 trail race.
Police have not given an official cause of death but from the steep course profile near the start, I'll bet she either fell off something or got a heart attack from trying to run too hard up a hill.
The lesson here is to never run an ultra.
