Rocky Mountain Tri-Fest Gravel

Rocky Mountain Tri-Fest Gravel is a family-focused multi-sport event held at Boulder Reservoir in Boulder, Colorado. The event was established in 2023 and offers races designed for adults and children, with formats that range from shorter sprint distances to youth-focused options.

Distances and formats include:

  • Sprint gravel triathlon
  • Super Sprint gravel triathlon
  • Mini distance for younger participants
  • SSS distance for younger participants

The Sprint and Super Sprint gravel triathlons use bike courses on the gravel roads that surround the reservoir. Those roads are described as graded and smooth, so participants may use a variety of bikes, including road bikes fitted with wider tires.

The Mini and SSS distances were created for younger members of the family; adults are welcome to accompany them. These shorter distances take place entirely inside the reservoir area and emphasize a recreational, fun approach rather than competitive complexity.

The event is presented as a community-oriented production that includes multiple race formats suitable for families and mixed-age groups. The listed venue address is Boulder Reservoir, 5565 51st St, Boulder, Colorado 80301. Visit the organization's website for the most recent information.
