USAT Aquathon Swim Run

The USAT Aquathon Swim Run is a multi-distance swim and run event held at Beaver Lake in Sammamish, Washington. The event is scheduled for August 2, 2026, at Beaver Lake, 25201 SE 24th St, Sammamish, WA 98075.

Race options include:

Certified lifeguards will be on the water during the competitive swims. Swim courses are set with color-coded buoys and athletes are required to swim clockwise around the buoys; colors distinguish each swim distance. The run course follows the same route used for the Beaver Lake Triathlon course and the overall course is marked with orange route arrows, elevated signs, and orange streamers.

Registrations include a long sleeve dry release event T-shirt and a finisher medal for those who complete their race. Packet pickup is offered the day before the event at Flatstick Restaurant and Grill, Redmond Town Center. All athletes must hold a current USA Triathlon membership; one-day USAT memberships are available for this event. Visit the organization's website for the most recent information.
