Sanders: Time to get your fat bike out

Mountain Biking with Keith

It looks like winter is finally arriving. That means it’s time to start thinking about getting your fat bike out and continue pedaling! Fat bikes are a blast. There is something about being able to mix up the winter activities by adding the fat bike to the mix. We live in a winter playground. Fat biking, downhill skiing, backcountry skiing, snow shoeing, snowmobiling, skate skiing and more. Sometimes the hardest thing is simply deciding which one to do.

Winter Park and Grand County are very unique to fat biking. Most areas are limited to a few trails that are contusive to fat biking due the lack of grooming or compaction. Here we have a huge amount of options, primarily due to the snowmobile grooming, snow mobile use, fat bike enthusiast packing trails and areas like Snow Mountain Ranch and Devils Thumb that have fat bike trails in addition to world class cross country skiing.

The type of trails tend to vary as much as summer if not at times a bit more. Snow conditions, trail widths and compaction from other users are just some of the factors that help create and mold your experiences. I prefer packed snow a day or so after a storm vs. new. Colder (i.e. freezing or below) offers better traction then warm. I tend to look at trails as following into three types. This is summarized but will give you an idea of options. Those are compacted roads and compacted trails by vehicles such as snowmobiles as well as singletrack created by skiers and other fat bikers.

The easiest of all trails tend to be USFS and county roads that have been compacted by motor vehicles, snowmobile or other means of motorized transportation. These tend to be the most compacted which offers the greatest traction while being the least technical. If you have never been fat tire biking before then these types of trails may be the best place for you to begin. Examples of these type of trails would be St. Louis Creek Road, Elk Creek Road, Vasquez Road, Little Vasquez, Fraser River Trail and USFS 159 to name a few.

The next level of experience and difficulty are those compacted predominately by snowmobiles and skiers. These tend to ride like wide singletrack. Difficulty levels can increase depending on the compaction of the snow. Hard pack and the bike will roll pretty fast, sometimes faster than on the dirt. If the snow is a bit loose then you will be challenged a bit to keep traction. If you have experience on a mountain bike then these will be a fun but good challenge for you. Examples these trails would be D4, Blue Sky and Sunken Bridge.

True singletrack is typically created by skiers, fat bikers, and snowshoe users. This can be the highest difficulty level as the compacted area is often less than 18” wide and sometimes as narrow as just a few inches. Fat Bikers call it riding the beam. Even the best riders slip off into the deep snow or take a tumble. Examples of some singletrack would be Crosstrails, Winter Woods, Ditch Trail, Sun Dog and Sunset Pink as well as others.

If you haven’t been out on a fat bike then you should. Start easy and then work up to harder difficulty levels. The bikes can be a lot of fun but as with any sport start within your ability and when you are ready explore greater challenges.
