The Original Growler Epic Bike Race in Gunnison Colorado

If you’re an experienced mountain bike rider looking for a challenge this Memorial Day weekend, you might want to consider riding in Gunnison’s notorious Growler Bike Race, a 64-mile ride that is often considered one of the most difficult in the industry. You’re even asked to check a box stating you’re an experienced rider upon registration!

What makes the Growler so difficult? As opposed to the Leadville 100, which is predominately fire road and double track, the Growler offers loads of classic and challenging singletrack and a climb of 4,000 feet for each loop—broken up, of course. There is almost never ending pedaling during this isolated, backcountry race as you wind your way around the ever-undulating Hartman Rocks trail system, just a few miles from downtown Gunnison. If this sounds a little too intimidating, know that these techy runs are broken by fast, flowy trails.

In classic Colorado style, the race ends back downtown where a party with food, drinks, and awards awaits and where bikers can celebrate their accomplishments.
