Course Details

The Columbia River Half Iron is a triathlon with a 1.2-mile swim in the Columbia River, starting from knee-deep water at the Vantage Boat Launch. This is followed by a 56-mile bike ride, described as a slightly hilly out-and-back route toward Ellensburg. The event concludes with a 13.1-mile run down to the Wanapum Reservoir Dam.
