The 2025 IRONMAN 70.3 Washington Tri-Cities is a landmark, late-season event in the Heart of Washington Wine Country, where the wine flows like water and the sun never stops shining. The Tri-Cities is truly an outdoor recreation mecca, thanks to its endless network of waterways, miles of hiking trails, and 300+ days of sunshine. The IRONMAN 70.3 Washington Tri-Cities offers easy race logistics and a centralized venue. On race day, you will take on a 1.2-mile downriver swim in the iconic Columbia River, a 56-mile rolling bike through scenic wine country, and a flat, 13.1-run through parks and on paved trails, finishing at a festive finish line at Columbia Point Park. Go with the flow in Tri-Cities, Washington, the perfect backdrop for your end-of-summer race-cation.
