The competition raised nearly $1million for various charities and featured a half-mile ocean swim, an 18 mile out-and-back bike course, and a 4-mile out-and-back run course.

The course wound through some of the most beautiful scenic roads in Malibu, with dramatic views of both the mountains and the Pacific Ocean.
