White Mountains Triathlon

The White Mountains Triathlon festival takes place at Echo Lake in Franconia Notch State Park and includes Sprint, Olympic and Half distance events. All swims occur in Echo Lake and the finish line is located on the lake beach. Wetsuits are mandatory for all races and must comply with USAT thickness rules.

Swim starts use a time trial format with athletes starting five seconds apart; start order is self-seeded by swim ability and athletes stage on the beach in numbered groups. The transition area opens on race morning and closes 20 minutes before each race start. The event is USAT sanctioned and requires either an annual membership or a one day USAT license.

Bike courses traverse local roads and include a recurring King of the Mountain climb on Rt 141 / Butterhill Rd at different mile markers for each distance. Aid station availability:

  • Sprint: no aid stations on the bike course
  • Olympic: aid at miles 8 and 15 with water and Gatorade bottle exchange
  • Half: aid at miles 8, 26 and 46 with water and Gatorade bottle exchange

Run courses use paved recreation trails in Franconia Notch State Park with scenic landmarks and finish beach side at Echo Lake. Run aid stations provide water, Gatorade, Untapped energy, GU energy chews and bananas. Awards are distributed at the post-race awards tent and finish line photos and finisher videos are provided after the event. Visit the organization's website for the most recent information.
