Some of the nation’s best athletes will run, swim and bike their way through San Diego this weekend, beginning and ending in Point Loma and stretching down San Diego Bay, as the inaugural San Diego Triathlon Classic commences Saturday, Oct. 10. “This is the only [U.S.A. Triathlon] -sanctioned Olympic distance race in San Diego,” said Rachel Gordon, director of marketing and sales of Moment Cycle Sport. “It’s the only race that has a full swim, bike and run.” The race will begin and end at Liberty Station. Nearly 700 racers will swim 1,500 meters in San Diego Bay, bike for 40 kilometers around the Peninsula and run for 10 kilometers — the distance necessary to make the event a U.S.A. Triathlon (USAT) -sanctioned race. “Having it be a USAT-sanctioned race puts a little bit more prestige on the race and gives athletes who are USAT members the ability to collect points in their age group to be ranked nationally,” Gordon said. “Through those national rankings, they can qualify for the national team as well as the world team.” The Olympic distance race starts at 6:30 a.m., with the sprint race starting 30 to 45 minutes later. The sprint race is half the distance of the Olympic distance race. “It’s pretty high competition in the sprint event by people who only train for the quick, fast races,” Gordon said. In the classic, racers will compete on a unique and challenging course. Along the way, racers will swim under the Harbor Drive pe­destrian footbridge, bike through the Naval Base Point Loma sub base and up to Cabrillo National Monument and run along the water and by the USS Recruit. “All of us at the shop are tri­athletes ourselves, and we just wanted something different,” Gordon said. “Triathlon was born in San Diego, and it’s something that we’re all pretty passionate about.” Gordon said the bike portion is the race’s most challenging. Part of the 10-kilometer ride is a three-quarter-mile trek up McClelland Road to Cabrillo National Monument. Gordon said the race is very spectator friendly and that there are seven different points along the course from which the public can watch. She said the best spot to catch a lot of action is in the transition area on Farragut Road behind Liberty Station. “It’s where the finish line is, where the expo will be and where racers will be exiting the water, going in and out on the bike, going out on the run and finishing the race,” Gordon said. On Friday, an expo on the lawn next to Cushing and Farragut roads will precede the race. The expo is free and will go from 2 to 7 p.m. Festivities will also follow the race on Saturday. There will be award ceremonies, entertainment, refreshments, vendors and exhibits to go along with a beer garden. On race day, portions of Farragut and Cushing roads will be closed from 6 a.m. to noon. A number of other roads will be closed from 6 to 9:30 a.m. A list of closures can be found at momentcyclesport.com.
