Tri-Cities & Yakima Area Triathlon Events

The Tri-Cities anchor Eastern Washington's triathlon season. Ironman 70.3 Washington on the Columbia River in Richland is the centerpiece — one of the region's fastest courses, with a downriver swim, flat bike, and full-sun run through the Hanford reach. Plutonium Man and the Righteous Richland Sprint serve the local field earlier in the season, and the Columbia River Half Iron in Vantage adds a canyon-wall bike loop to the menu. Lake Chelan extends the corridor north. Walla Walla's Onion Man closes out the season. Hot summers, tailwind optional.
