The Auburn Triathlon is held annually in Auburn, CA (the Endurance Capital of the World) and consists of the World’s Toughest Half (1.2 mile swim, 56 mile bike, 13.1 mile run), the Auburn International Triathlon (.9 mile swim, 24.8 mile bike, 6.2 mile run), the Auburn Mini Triathlon (500 meter swim, 8 mile bike, 2.6 mile run), and the Auburn Long Course Aquabike (1.2 mile swim and 56 mile bike).

Each event offers calm water, canyon scenery, mild temperatures, and a low-key race environment.

You will swear you’re racing a Giro D’Italia stage! The setting for your run is the spectacular Auburn State Park – breathtaking views along the canyon rim, looking down at the American River.

You’ll enjoy a grass roots feel with a focus on delivering the best possible experience to each and every athlete. The Auburn Triathlon will be a weekend you never forget! Enjoy the fabulous T2 and Finish venue of the American River Canyon Overlook. with lots of spectator shade and multi-loop vantage points!
