The Ironman 70.3 Oregon endurance competition is making a highly-anticipated return to Salem for its fourth iteration of the annual event on Sunday.

Widely considered one of the fastest courses on the Ironman circuit, the Ironman features a 1.2-mile swim in the Willamette River, a 56-mile bike ride, and a 13.1-mile run. Last year, Lionel Sanders won the men’s pro division in 3 hours, 33 minutes 37 seconds. Danielle Lewis won the pro women’s division in 3:59:41.

Once again, this year’s event has sold out and is expected to draw more than 2,500 athletes and supporters to Salem. It will offer age group qualifying slots to the VinFast IRONMAN 70.3 World Championship in November 2025 in Marbella, Spain.

Travel Salem is the main host of the event, along with City of Salem, Travel Oregon, the Willamette Valley Visitors Association, and Sport Oregon. It estimates that Ironman 70.3 Oregon will generate approximately $11 million in economic impact for the Salem area.

The race begins at 6 a.m. Sunday and is expected to wrap up around 4:30 p.m.

The race begins with the 1.2-mile swim in the Willamette River, a 56-mile bike ride from River Road S. toward the Ankeny National Wildlife Refuge, and finishes with a 13.1-mile run through Salem’s Minto-Brown Island Park.
