For more than 20 years, an incredibly special event has taken place every October at La Jolla Cove in San Diego, Calif known as the San Diego Triathlon Challenge. On Oct. 20 more than 700 able-bodied athletes, celebrities and challenged athletes came together to participate in this triathlon and weekend festival to help raise money for the Challenged Athletes Foundation (CAF). The CAF Foundation raises money to provide challenged individuals of all ages with the tools necessary to compete in sport.

This year’s even featured four-time Ironman world champion Chrissie Wellington, 2013 Ironman Hawaii 7th place finisher Meredith Kessler, 2013 Ironman Hawaii runner-up finisher Luke McKenzie and Ironman Australia champion Luke Bell among the many participants in the day’s festivities. In addition to the 1 mile open-water swim, 44-mile bike ride and 10-mile run triathlon, participants could also take part in the four-hour-long Tour de Cove spinning marathon, a 5K fitness walk, silent auction and BBQ.

This year’s event was especially poignant, as several athletes affected by the 2013 bombings at the Boston Marathon took part in the race and the weekend-long festival.

So far, this year’s event has raised well over a million dollars for the foundation, but fundraising is still going on. To donate, click here. For more information at the CAF foundation, click here.
