Rocky Mountain Tri-Fest

August 9, 2025 @ 7:00 AM

Rocky Mountain Tri-Fest is Colorado’s newest Multisport event, catering to the whole family. With events for everyone from mom and dad looking to try their hand at a gravel triathlon, to children looking to do their first triathlon.

The Sprint and Super Sprint gravel Tris are beginner friendly with the bike course on the gravel roads surrounding the reservoir. The road are graded and smooth, so you can use almost any bike, even a road bike with wide tires.

The Mini and SSS were created for the younger members of the family, but adults are more than welcome to tag along. These distance take place entirely inside the reservoir, and are 100% about having fun.

Sprint Triathlon
750m swim / 12.4 mile bike / 3.1 mile run
If you are new to triathlon, this is the distance for you! Compete in the fastest event offered, with the majority of participants racing in this distance!

Super Sprint
400m swim / 6.2 mike bike / 1.55 mile run
A perfect distance for your first tri or for those just looking to have some fun.

This event is all about fun. The swim is along the shoreline so participants are welcome to wade/ walk along the bottom, or even just walk along the edge and get their feet wet. Lifejacket, floatie and armbands are welcome.
