Zac Efron participated in the Nautica Malibu Triathlon this weekend in Malibu. He was joined by his brother Dylan and Olympic swimmer, Conor Dwyer.

The annual event is held in support of Children’s Hospital Los Angeles. Last week Zac visited with patients at Childrens and asked fans to donate to support the hospital.

This is the second year Zac and his friends have participated in the triathlon!
