CARbon-Free Challenge
Formerly known as the Commuter Challenge, the challenge encourages the use of alternative forms of transportation.
Transportation remains one of the largest sectors of emissions across Routt County and greater Colorado. Not only do the emissions contribute significantly to climate change but transportation pollutants can also have adverse impacts on human health, such as asthma, reduced lung capacity, and respiratory illness.
Every year, YVSC holds the CARbon-Free Challenge (formerly known as the Commuter Challenge) to encourage the use of alternative forms of transportation, like biking, walking, or even roller blading, in order to expose people to more fun and healthy modes of transportation and reduce emissions. Participants log their miles travelled using alternative forms of transportation as solo riders, families, or adult teams for the chance to win prizes provided by local businesses.

2025 Event
Spring is here, and we’re all looking forward to days spent outside, connecting with nature and with one another. That’s why we’re excited to bring back the CARbon-Free Challenge, taking place from June 1-30.
As in years past, participants will log their miles for the chance to win awesome prizes from our local sponsors and have the ability to take part as a solo rider, family, or adult team. Participants can log miles for commuting, running errands going out, etc., all while using an alternative form of travel (e.g. walking, biking, longboarding, rollerblading, etc.).
How it works
Register for the challenge and commit to using alternative transportation (walk, bike, longboard, etc.) at least once per week from June 1-30. If you are competing as a team, each team member needs to register.
Register in 1 of 3 categories:
- Solo Participant.
- Family Team (doesn’t have to be the same family but must have at least one child and one adult on the team, up to six members).
- Adult Team (teams can include up to four members, you may have many different teams from the same company or a group of like-minded friends).
Log your miles
Google Sheet — All instructions for use of the Google Sheet can be found on the first page.
Please note that this year, we will not be collecting miles on Strava due to technical complications with the app. If you love Strava, you’re welcome to continue to use the app for your own tracking, just be sure to enter your miles in the Google Sheet at the end of each commute.
Compete against other teams and participants to see who can log the most alternative transportation miles/trips for the chance to win awesome prizes.
Participants can expect weekly emails during the challenge with leaderboard updates and upcoming mini events/challenges. At the end of the challenge we will celebrate our winners with a great party and a chance to receive prizes!
