SYDNEY (AP) -- Olympic gold medalist Emma Snowsill has retired from competitive triathlon at age 33.
Snowsill won the 2008 Beijing Olympic triathlon, won gold at the 2006 Melbourne Commonwealth Games and is a three-time world champion.
In announcing her retirement on her website Friday, Snowsill said "my health has really struggled over the last four years. Ultimately my body helped make the decision for me -- that it didn't have what it needed to compete at the highest level on the world stage anymore."
She said triathlon "has been a huge part of my life and I will in some way always be connected to it, however now it feels right to explore life outside of only competing."
