Ironman 70.3 Omaha

Test your limits at IRONMAN 70.3 Omaha — a thrilling course that starts with a rare swim in Lake Cunningham, cruises through scenic farmland, then runs across the Bob Kerrey Bridge and back, fueled by downtown’s electric energy.

What to expect

The 70.3-mile triathlon format includes a 1.2-mile lake swim, a 56-mile bike course, and a 13.1-mile run.

Why go

IRONMAN 70.3 Omaha gives athletes and spectators a distinctly local course: open Nebraska countryside, a landmark bridge crossing over the Missouri River, and a downtown-adjacent finish. It is built as a showcase of Omaha’s outdoor spaces and sports-hosting energy, with Lake Cunningham serving as a rare and memorable starting point.
