what they’re saying
I have been racing triathlons in Southern California since the late 1970s, and one of my all-time favorite events is the Orange County Triathlon in Mission Viejo. When you combine epic courses with great history, the outcome tends to be a classic event!”Bob Babbitt, Host of Babbittville Radio
