Frisco Triathlon

The 2021 Frisco Triathlon is sold out. We will enroll people from the waitlist when and if the COVID-19 group gathering guidelines change. More information about the waitlist can be found under registration below.

Event Info

Are you looking for a new challenge this summer? Register for the 7th Annual Frisco Triathlon on Friday, July 9, 2021 featuring stand-up-paddle boarding, mountain biking, and trail running. This twist on a triathlon is open to all ability levels and encourages athletes to take on a new multi-sport event. The Frisco Triathlon was named “Best Triathlon” in Elevation Outdoors Magazine’s reader poll, 2016 Best of the Rockies.

The Frisco Triathlon is moving to a Friday in 2021. With the volume of people we see at the Frisco Bay Marina on the weekends, we feel that we can provide the best racer experience, as well as provide a safe environment for other Marina guests, but moving the race to a Friday.

Course Details

Racers will start the SUP leg (3k) of the event at the Frisco Bay Marina at 9:00am and make their way across Dillon Reservoir to the Pine Cove Campground where they will transition into the mountain bike leg (12k) of the race. The mountain bike portion of the race will consist of inland single track trails and the trail running leg (5k) will consist of the Frisco Peninsula trail offering amazing views of the Dillon Reservoir and the Ten Mile Range and will also guide racers through some of the inland trails as well.

  1. Paddle: Start at the Frisco Bay Marina > go around buoy > finish at Pine Cove boat ramp.
  2. Bike: See course route in map. We recommend that you have intermediate mountain biking skills to compete in this event. A mountain bike is required to race.
  3. Run: See course route in map below.


If you are planning pre-ride/run the course, it is highly recommend you print out the course map, course description listed above, and this map of all of the trails on the Frisco Peninsula. The course can be tricky to find on your own as some of the trails are unmarked or have confusing intersections. Please know that the course will be marked extremely well for the race.

Also, if you do pre-ride/run the course, we recommend you park at either the Frisco Adventure Park or in the Two Below Zero parking lot that is located just after you turn from Recreation Way onto the Campground Road.  This is a mulch lot and is labeled “Two Below Zero Parking”.  If you choose to park at the actual transition area, you will have to pay a $7 USFS fee per vehicle.
