Earlybird registration is OPEN!

The 2025 multisport season is just around the corner! Take advantage of our incredible pricing, and register by February 10 for the 7 great events listed below!

We are excited to announce the addition of two amazing events to our calendar. The Fishers Sprint Triathlon (May 17) will be happening at Geist Waterfront Park. And the Go Girl Triathlon (July 26) is back and better than ever at Red Bridge Park in Cicero, IN.

Lastly, we regret to announce that we will not be hosting Tri Indy. Due to rising costs, and slowly decreasing attendance, it has become unfeasible for us to proceed. This decision was not made lightly, and is incredibly disappointing to us. We are so grateful for the support our competitors have given us since this race began in 2008.
