NEW YEAR - NEW VENUE!

This year, we’re hosting 4 cross-country fat bike races on different courses at the Round Valley Trails in Park City, UT.

These races follow traditional Mid Week XC format - mass starts, 45-60 minutes of racing, and circular courses with one start and one finish. We welcome fat bike riders of all ages and abilities, and our mission is to support all levels of individual skill-building and mountain biking goals.

Sponsor the Fat Bike Series

Our sponsors are the backbone of the Mid Week Fat Bike & MTB Series. Without their support, we wouldn't be half the race series we are. Our goal with sponsorships is to help offset race production costs so that 100% of the revenue raised from registration fees can go directly to supporting other Bike Utah programs.

If you would like to sponsor the 2026 Fat Bike Series, please connect with us!

We are looking for the following sponsors:

  • Series Sponsor - $4,000 for the entire series - 1 available

  • Race Sponsor - $1,000 per race - 4 available

  • Bike Demo Sponsor - provide demo fat bikes for each race - 3 available

  • Product Sponsor - provide swag for each race giveaway - 5 available

  • We will not be riding on trails that have lights overhead. Please have a bright handlebar light and/or a bright helmet light.

  • Jibe Cycleworks has got you covered! Ride one of their Chubber fat bikes. Limited numbers and sizes are available, so reserve your bike now.

  • For these races, fat tires are any tire that is 3.8” wide or greater. Please DO NOT bring a skinnier tire bike. We are riding AT A NEW VENUE on community trails that are groomed/maintained by a community trails foundation, and we will be good stewards of these trails. RUTS SUCK all around, and we can’t take a chance that the trails won’t support a higher PSI tire.

  • No one is here to qualify for the Olympics or win a big prize purse. Those who take home medals (or at least high fives and kudos) will be the ones who are the most friendly and supportive of all riders on course. Race results may not necessarily be available on race night, but some great sponsor-provided swag will be!
