IRONMAN Santa Rosa is the only full distance triathlon in the state of California and in 2020 we will be celebrating 30 years of IRONMAN distance racing in the region.

Santa Rosa is where beer city meets wine country. It's also a hub for cycling, foodie paradise and an active urban culture. There is so much to experience for athletes and their families.

This event honours a long history of triathlon in a wonderful community that embraces the athletes for the experience of a lifetime.

The 2020 IRONMAN Santa Rosa will offer 40 qualifying slots to the 2020 Vega IRONMAN World Championship in Kailua-Kona, Hawai'i.

Ironman Santa Rosa route

The split transition race begins at Lake Sonoma, nestled in the beautiful mountains of Northern California. The 2.4-mile swim is a two-loop course taking place in the calm, clean Lake Sonoma. Athletes will transition to their bikes, setting out on the 112-mile course featuring gentle rollers as they ride through famous wine country and quaint towns. The City of Santa Rosa hosts transition two where athletes will begin a tree-lined, two-loop marathon along the Santa Rosa Creek trail. The finish line will take place at the new Courthouse Square park ideally located in downtown in Santa Rosa where great food and wine can be enjoyed by all spectators.
