You probably noticed that one of the studies presented at this year’s Annual Scientific Session showed sudden deaths occurred nearly twice as often in athletes participating in triathlons as in athletes participating in marathons: 1.5 per 100,000 versus 0.8 per 100,000. Investigators examined deaths that occurred in 2,846 triathlons featuring 922,810 participants. Nearly all the triathlon sudden deaths took place during the swimming portion of the event. 

Noting this unexpected differential, I've asked ACC Board members and officers to stick to marathons from now on.
