Millerton Lake Crows Nest Triathlon, 5k & 10k

The event takes place at Medow Campground in Friant, CA, with swim starts from the Millerton Lake Boat Launch and a central Transition Area. Course formats include swim, bike and run legs for multiple triathlon distances, as well as separate 5K and 10K running races that mix single track trail and paved road.

Notable course features:

  • Super Sprint Triathlon: 400 yd swim, 5.4 mi bike, 2.2 mi run.
  • Sprint Triathlon: 13.8 miles total.
  • Olympic Triathlon: 1600 yd swim, 21 mi bike, 6.2 mi run.
  • 5K run and 10K run; the 10K is two loops of the course.

Bike courses are described as out-and-back with rolling hills; the Olympic bike consists of two loops. Run courses combine single track trail and asphalt; some events use looped layouts and include an aid station on course.
