The 12th annual Kaiser Permanente Los Angeles Triathlon will be held Sunday, Sept. 25, with nearly 2,500 competitors kicking off the race with the swim portion in the ocean off Venice Beach.

This year’s field in the swim, cycling and run competition is made up of participants from 30 states, plus the District of Columbia, and 11 countries.

Presented by Herbalife, the Los Angeles Triathlon features the Olympic or Sprint distance competitions, a bike-only category or a 3-person relay team event.

One of the few point-to-point triathlons in the country, the Los Angeles Triathlon starts at 7:15 a.m. at Venice Beach with the ocean swim segment (0.9 miles for the Olympic distance and 0.4 miles for the Sprint distance). The bicycle ride segment – 24.8 miles (Olympic) or 14.1 miles (Sprint) – then begins at the beach, going through Venice, the Fairfax District, and into downtown Los Angeles. The race concludes with the run portion near STAPLES Center (6.2 miles, Olympic, or 3.1 miles, Sprint) through downtown, passing the Disney Concert Hall, and ending at L.A. Live! Nokia Plaza.

Professionals are competing for $40,000 in prize money and points in the Life Time Fitness Triathlon Series Race to the Toyota Cup, which connects the seven prominent Olympic-distance races in the United States and culminates in the Series championship on Oct. 2 in Dallas, TX. Elite amateurs (top three) and age-group racers (top 10) also have a chance to win a coveted spot in the Toyota Cup race in Dallas.

The professional field is led by Swedish Olympian and 2009 and 2010 champion Lisa Nord/n, and Australian Olympian and three-time L.A. Triathlon champion Greg Bennett. Bennett is now a U.S. citizen and will be trying for a spot on the U.S. Olympic team in London next year.

The cycle and run portion of the triathlon is managed in three sectors, with streets closing and opening in waves as the competitors move from Venice to downtown. To ensure the safety of the competitors, spectators and vehicular traffic, the Los Angeles Police Department and Department of Transportation officers will be monitoring intersections. Due to the race, South Venice Boulevard, from Ocean Front Walk in Venice to Motor Avenue in Palms, will be closed to traffic from approximately 6:50 a.m. to 11 a.m.
