June Lake Triathlon

Competition or Sporting Event
The swim

Started officially on 7/7/2007, the June Lake Triathlon was conceived by a triathlete who saw June Lakeas the most beautiful stage ever for a triathlon. Located in a beautifully scenic high alpine setting, the community of June Lake sits at 7,600 feet above sea level with breathtaking views of Carson Peak and the Sierra Nevada range surrounding the nestled cluster of high altitude lakes that include Grant, Silver, Gull and June.

The triathlon boasts crystal clear, clean water in a high alpine lake, a beautiful loop course on scenic roads circling the June Lake basin, and a mountainous trail run (my favorite kind) with majestic views of the surrounding mountain peaks. The event is held annually the weekend after the 4th of July.
