  • Steamboat Stinger MTB Race + Marathon | Honey Stinger

The Steamboat Stinger, now a Colorado classic, aims to provide a challenging backcountry race experience showcasing some of Steamboat Springs’ finest singletrack. The Steamboat Stinger is also a fundraiser for Partners in Routt County (local youth mentoring group) and the Trail Maintenance Endowment Fund.

In addition to the Saturday mountain bike race, we feature a full and half trail marathon on Sunday. These two events can be separate or, if you wish to take the ultimate challenge, you can participate in both – the 50 mile solo mountain bike race as well as the 26.2 trail marathon the following day. The male and female winners with the lowest combined bike and run times shall be crowned King Sting and Queen Bee.


Mountain Bike course

You can expect singletrack….lots of it. Beginning at the Howelsen Hill Ski Area in the heart of Steamboat Springs, the course takes an extended tour deep into the beautiful backcountry of Routt County before returning to the transition/finish area. Racers wind through open meadows, aspen forests and wild sage gardens offering incredible views of the surrounding peaks and valleys. It is a 50+ mile race composed of two 26.2 mile loops, 100% on dirt and 90% on singletrack.
