2025 Mid Week Fat Bike Series

On the snow and under the lights!

The Mid Week Fat Bike Series is comprised of 4 cross-country fat bike races on different courses at Soldier Hollow Nordic Center in Midway, 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 2025 Fat Bike Series as a Series Sponsor, Race Sponsor, Bike Demo Sponsor, or Product Sponsor, please connect with us.

  • We will likely have 2025 sponsors who provide fat bike demos on race nights. Check back to see if we can secure some great bike demo sponsors!

  • If you didn’t do it already as a part of your registration, you MUST have digitally signed a SHNC waiver to be allowed to participate. CLICK HERE to sign that waiver!

  • We are riding on groomed Nordic trails, and dirt, mud, rocks, etc do not play well with the grooming machine and the skate/classic skis that glide over these trails every day. You WILL NOT be allowed to participate if your bike is dirty (frame or tires) at all. If spring conditions pop up before our race series is over and you ride on dirt/mud, please clean your bike BEFORE you come to our event.

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

  • For these races, fat tires are any tire that is 3.8” wide or greater. You may choose to race on a skinnier tire, but please be aware that we will put you in a separate category to keep things fair for all riders.

  • 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!
