IRONMAN Washington Tri-Cities
IRONMAN 70.3 Washington Tri-Cities on 20 September 2026 swims 1.9 km in the Columbia River at Richland, rides 90 km through the vineyards of the Columbia Valley, and runs 21.1 km on the riverfront trails.
A river swim means current, and current means the two halves of the course are not the same swim. Sight often on the upstream leg and do not read anything into the split you see at halfway.
Eastern Washington is high desert, not the Seattle side of the state. Expect dry air, a big swing between morning and afternoon temperatures, and almost no shade. A cold start and a hot run in the same morning is normal here.
The bike is flat and fast through irrigated farmland. The wind funnelling along the valley is what decides whether this is a personal-best course or a long day in the aero bars.
