Rattlesnake Lake Triathlon
The Rattlesnake Lake Triathlon takes place over Labor Day weekend 2026 near North Bend, Washington. The event is presented as a sprint triathlon with individual and relay entry options and a limit on total participants.
Distances included:
- 1/4 mile swim.

The swim is held in Rattlesnake Lake, with water sourced from snow melt in the Cascades and the Cedar watershed. The bike course is a mixed road and trail route, described as roughly 3 miles of road and 7 miles of trail on the Palouse to Cascade Mountain bike trail; the surface includes limestone and hard packed dirt and a regular road bike is considered acceptable. The run is 4 miles, combining about 3 miles on an asphalt bike path and 1 mile on hard packed limestone or dirt through Rattlesnake and Cascades Park.
Entry options and pricing listed by the organizer include a full individual triathlon entry for $85 and relay options priced at $50 for two person teams and $45 per person for three person teams. Relay entries require USAT membership and relay participants are noted to receive a race T-shirt and a finisher medal.
