Wow, she was quite an accomplished triathlete, and it sounds like her spirit will live on in the lore of the sport.
She crashed during a race (but it was unclear if other bikes, peds, or car involved). I've heard about triathletes having heart attacks on the swim, but not sure if I'd heard of this... but, then marathoner Ryan Shay died at the peak of his career at the US Olympic trials just last year... so nothing is a given. Guess we all have to ride safe and enjoy the time we have here...
