The High Sierra Triathlon Club located in California’s Eastern Sierra trains in Mammoth, June Lake and Bishop, CA.  The Club was formed as a non-profit organization in March of 2005. We are recognized by USA Triathlon (USAT) as an official USAT club, and our membership is growing steadily. Our mission as a club is to encourage anyone and everyone to try the sport, provide continued support to those already established in triathlon, provide structured workouts for all members, provide opportunities for training and meeting training partners, and provide a fun, social atmosphere where everyone, regardless of abilities, feels welcome.

Annual Tri Club Membership costs $45, please sign up at imATHLETE. Club workouts are posted on our calendar. These are free to members or $5 drop-in for your first time to try. All activities are seasonal from May-September.  Other groups offer seasonal training opportunities with their own fees.  Mammoth Track Club offer run intervals on Tuesdays at 7am at Mammoth Track and Eastside Velo Club offers cycling workouts and groups year-round.

Whitmore Pool is open May-early September for lap swimming. Swim passes can be purchased there. Coaching services are offered and can be purchased for an additional fee from club coaches Alana Gillmore
