Beaver Lake Triathlon

The Beaver Lake Triathlon is a multi-discipline event held at Beaver Lake Pavilion in Sammamish, Washington. The full course combines an open-water swim in Beaver Lake, a road bike segment that climbs Duthie Hill and returns on a lollipop route, and a neighborhood run around the lake that finishes through forested sections.

Distances for the full triathlon:

  • Swim: 1/4 mile in Beaver Lake
  • Bike: 13.4 mile road course up Duthie Hill and back (lollipop)
  • Run: 4.3 mile flat loop around Beaver Lake

The event offers several race formats including full triathlon, duathlon, aquathon, aquabike, and relay teams. Registration packages note inclusion of a finisher medal, a long sleeve dry release race T-shirt, entry to the pre-race pasta feed, and posting of results on the USAT website. All registered athletes must be United States Triathlon (USAT) members; a one-day USAT membership option is available on the registration page.

Additional event elements published by the organizer include a live-streamed pre-race safety briefing and a pre-race pasta feed at Redmond Town Center Flatstick Restaurant and Grill.
