World Class Events

We pride ourselves as a grass roots organization and make it our goal to provide athletes and sponsors with a world class experience. We are honored to have many of the most recognized elite athletes in the sport call both “Bonelli” and the “LA Series” a regular stop in the annual triathlon circuit.

An Amazing Venue

Bonelli Park is the perfect venue for the ultimate triathlon course. The lake in the middle of LA is easily accessible, the bike course has rolling hills and no left turns to navigate against traffic. The run is a mixture of cross county and beautiful scenery.

Fun for Everyone

Our event has a super relaxed setting were spectators can mingle with the athletes afterwards and watch the run and bike course — all from really close to the finish line. We also get some of the biggest names in the sport competing in every event. It’s the perfect mix.
