* Here's good information if you are here riding on Thursday and Friday.

Please Do NOT Ride on ANY Area Snowmobile Trails

Here's Why - Mostly for safety reasons, a local ordinance prohibits those biking and skiing from doing so on the snowmobile/ATV trails and snowmobiles/ATVs from being on the skiing and biking trails. In the case of riding your bike on the snowmobile trails, there is a fine for doing so. But, mostly the ordinance is related to safety--yours!

Where You CAN Ride on Thursday and Friday

The Seeley Hills Trails are groomed and ready for Fat Bikers. There is singletrack as well as ski trail you can use. You can park and get on the trail system on Old "OO" Road--which is a right hand turn about a quarter mile after you turn onto County "OO" from Hwy 63 in Seeley. If you have questions, stop by Riverbrook Bike & Ski in Seeley (and in Hayward) and get more details there.

You can again bike on the Seeley Hills Trails (above), and ...

The Fat Bike Birkie provides a one-day-a-year chance to ride your fat bike on the groomed, snow-covered American Birkebeiner Ski Trail! Fat bikes and mountain bikes are otherwise not allowed on the snow covered, groomed trail system because our priority is giving skiers the best possible experience all winter. This event is a one day exception to this rule and is for fat bikes only.

Course Map

Snow Conditions and Course

The Birkie Trail usually receives fresh snow during March and goes through a daily thaw and freeze cycle, resulting in a very compacted snow base great for Spring skiing. The ABSF continues to groom for cross country skiing during this time.

We believe these conditions can allow the Fat Birkie Birkie race to take place without damage to the trail. If conditions such as an early thaw occur and damage to the trail appears possible, the race course will be moved to neighboring forest roads.

Snow and trail conditions before the Birkie ski race in February can be softer and more vulnerable to damage. For that reason, and because of the far greater numbers of people skiing on the trail, Fat biking on the Birkie Trail system is not permitted at any other time during the winter.

The long and shorter Fat Bike Birkie races will take place on the northern half of the Birkie Trail system, between Telemark Resort and the "OO" trail head. Cross country skiing will be available on the Birkie Trail south from "OO" on race day. The northern trails will be regroomed Saturday night, following the Fat Bike Birkie, and available for skiing the next day and through the remainder of the ski season.

We post trail reports all during ski season at birkie.com/trail and will continue to do so up to the Fat Bike Birkie to keep you well informed. Trail reports will be posted on this page as well.

Tire Size Requirements

Fat Bikes must have 3.7" diameter or greater.

* This requirement will be monitored at the event by the sizes indicated on the tires used.

What is Fat Bike?

Wide rims, extra-large tires, and weirdly-dimensioned frames to make it all fit together define a Fat Bike, a cycling subcategory that’s garnered a serious following since 2012. Bike shops report selling out of fat-bike stock.

What is the appeal? From improved traction on dirt to flotation when riding through snow, the obese tires let a bike roll where it has not rolled before. The wide rubber — some fatty tires are 4+ inches across, or twice as wide as most mountain-bike tire tread — adds notable grip on the ground, and the extra surface area does not allow the wheel to sink as much into soft surfaces like snow or sand.
