Beginner Fat Bike Ride at Mirror Lake

Interested in checking out FAT BIKING at Mirror Lake?

Come out Sunday November 28th, 2021, meet at the main parking lot at 1pm and we will ride a mile loop around Mirror Lake, then head out for 2 more miles of rolling trails through the woods.

Most of the trails have been snowshoe packed, or groomed with our SnowDog, but there may be some sections of fluffy goodness for us to push our bikes through.

If you haven’t already filled out at 2021 CMBR waiver, please sign one online before arriving. Thanks!

Free Training: Building Berms and Repairing Rollers.

Join CMBR and Happy Trails on Tuesday, August 31st, 2021 from 5-6:30pm for a professional trail-building session on berm and roller shaping and repair.

Ben’s Bike Playground is nearly complete, and CMBR is here to teach YOU how to BUILD, RIDE and MAINTAIN the new jump lines and pump track.

We realize this may be an awkward time for folks, but we are trying to catch the Happy Trails builders before they move on to their next project.

We expect Ben’s Bike Playground construction to be complete by mid to late September. After that we will wait for a couple weeks of dry weather for the trails to harden before opening.

Tuesday July 6, 2021- CMBR Kids CANCELLED

We were really hoping the skies would dry up for our first official CMBR Kids session. While the rain has let up some, we recognize that standing around in the rain for our first lesson would not be the fun night we were looking forward to. You are welcome to come ride the trails with your families but we are cancelling tonight’s session. We will see you on Thursday!
