IRONMAN 70.3 Washington Tri-Cities

The IRONMAN 70.3 Washington Tri-Cities is a late-season triathlon held in Richland, Washington. Located in the state's wine country near the confluence of the Snake, Yakima, and Columbia Rivers, the event base is situated at Columbia Point Park. The region typically experiences high air temperatures of 70 °F (21 °C) and low temperatures of 52 °F (11 °C) during this period.

The race consists of the following disciplines:

  • 1.2-mile swim
  • 56-mile bike
  • 13.1-mile run

The event begins with a downriver swim in the Columbia River, which provides a current-assisted course. The water temperature averages 70 °F (21 °C). Following the swim, participants embark on a rolling bike course that travels through local orchards and vineyards. The final leg is a flat run held on paved trails and through shaded parks along the riverfront.

This event serves as a qualifier for the 2027 IRONMAN 70.3 World Championship. It features a centralized venue designed for simplified logistics. The Tri-Cities area is accessible by car from Spokane, Seattle, and Portland. Visit the organization's website for the most recent information.
