Midsummer and Merry Masher Races


The mid-winter Merry Masher fat bike race is the main membership drive and fundraiser for Chugach Mountain Bike Riders and proceeds go to support the improvement of the Mirror Lake Singletrack. It is usually held on the weekend between Christmas and New Year’s.

Here’s a map of the proposed 2020 winter race:
