Her next big race: the three-day, 319-mile Ultraman Canada.

Dorette is a former head coach for the Nike Women's Full and Half Marathon and the San Francisco AIDS Foundation “Greater than One” full and half marathon training programs. She serves as track and running coach for the Golden Gate Triathlon Club.
