To the Editor: In their Research Letter, Dr Harris and colleagues1 provided information about sudden death during the triathlon. In light of the increasing participation in triathlon events, as well as in open water swimming, more athletes might require urgent medical care. Further understanding of the causes and settings of sudden death in such competitions could greatly assist in medical team preparedness. We would therefore like to consider the possible mechanisms of deaths during the swimming part of the triathlon.
