Organizers are gearing up for Sunday’s Orange County International Triathlon in Mission Viejo.

The Sept. 27 race kicks off at 7 a.m. and ends by 11 a.m. The race is an Olympic distance course consisting of a 1-mile swim in Lake Mission Viejo and a 25-mile bike ride beginning on Marguerite Parkway, north to El Toro Road and out through Santiago Canyon. The race ends with a 10K run that starts on the Aliso Creek Bike Trail and follows various trail systems leading back to the Lake.

Organizers are excited about the race’s return to Mission Viejo and what is expected to be a spectacular finish.

“The Finish Line is at the Lake this year and should make for a beautiful backdrop with the athletes running under the 50 state flags after they enter the Lake parking lot and head to the finish,” said race director Bill Leach.
