Welcome to HSTC

Work out in the High Sierra with us!

June Lake Triathlon Course

The HSTC is a non-profit organization developed to provide a fun and supportive environment for triathlete training in the beautiful Eastern Sierra. Based in Mammoth Lakes, California we train in June Lake, Mammoth and Bishop.  Join us for workouts each week, group races, special events, races and clinics. We also offer individual athlete coaching. We offer outdoor training events mid-May through September. Examples are lake swims, bike time trials, mock tris and run workouts. These are free to members ($5 if not), so join today.


Join us for training camps for June Lake Triathlon and the summer season!

The High Sierra Triathlon Club is working to improve bathroom and public facilities at June Lake Beach this year.  We hope to collaborate with USFS and Inyo Recreation/CLM-Services to make better facilities for ALL!

The June Lake Triathlon helps raise funds for these projects.

The June Lake Triathlon also features an online fundraiser for Disabled Sports Eastern Sierra. Committed to making fitness accessible to everyone, DSES changes lives.
