IRONMAN 70.3 Washington Tri-Cities

IRONMAN 70.3 Washington Tri-Cities is a late‑season triathlon held in Richland, Washington, at the confluence of the Snake, Yakima, and Columbia Rivers. The event takes place in Washington wine country and uses a centralized venue to simplify race logistics.

The race course comprises three standard 70.3 legs:

  • 1.2-mile downriver swim in the Columbia River
  • 56-mile rolling bike through orchards and vineyards
  • 13.1-mile flat run through parks and on paved trails, finishing at Columbia Point Park

The region is noted for more than 200 wineries within 50 miles, an extensive network of waterways and hiking trails, and a high number of sunny days. Typical event conditions listed include an average water temperature around 70°F (21°C) and air temperatures that can range near 50°F to 78°F (10°C to 25°C). The course highlights include riverfront trails for the run and scenic vineyard and orchard sections on the bike. Visit the organization's website for the most recent information.
