This year Sonoma County will host two important triathlon races: Ironman Santa Rosa (May 11) and Ironman 70.3 Santa Rosa (July 27). Both events are major occasions in the triathlon world, bringing competitors and fans from around the globe.

At May’s Ironman Santa Rosa, entrants from every state in the nation and eleven countries will be competing for 40 qualifying slots at the 2019 Ironman World Championship in Kailua-Kona, Hawaii on October 12, 2019.

In July, competitors in the Ironman 70.3 Santa Rosa hope to win one of that event's 30 qualifying slots to the 2020 Ironman 70.3 World Championship to be held next year in Taupo, New Zealand.

Both Ironman and Ironman 70.3 offer plenty of athletic challenge and excitement, food, music, and many fun events—for racers, sure, but also for locals, visitors, and anyone who wants to watch and celebrate world-class athletes.

A Brief Ironman Primer

Both Ironman Santa Rosa and Ironman 70.3 Santa Rosa consist of three traditional triathlon events: a swimming race, a bicycle race, and a running race. Events are completed in that specific order, back-to-back with no break.

For the May 11 Ironman, the competing distances are a 2.4-mile swim, a 112-mile bicycle race, and a 26.22-mile marathon. That's a total of 140.6 miles, sometimes referred to as a Full Ironman.

In July's Ironman 70.3, the traditional triathlon events of swimming, bicycling and running are half the distance of the Full Ironman, or 70.3 miles. The 70.3 is sometimes called a Half Ironman.

Both the May Ironman and the July Ironman 70.3 utilize the same courses, offering a spectacular wine country backdrop that will enthrall racers and spectators alike. The swimming races take place at Lake Sonoma; bicycles wend through Alexander, Russian River and Dry Creek Valleys; and the marathon and half-marathons are run along tree-lined Santa Rosa Creek trail. There are many beautiful locations for spectators who want to watch the action (see “Where to Watch,” below).

The festive finish line for both events: Santa Rosa's Courthouse Square, where the crowds will be primed for celebrating.
