The Rock Cobbler is a stupidly challenging ride bordering on a race. It was conceived by madmen, on barstools late into the night. Gravel Ride? Sorta…

“Cobbler” planning started in the fall of 2012 on a cow trail, when 3 buddies wanted to showcase a very mixed terrain and riding style they loved. Rock Cobbler 1.0 was launched in February of 2013 with 40 riders. Since then, the event's reputation for dishing out a punishing and shenanigan riddled adventure has grown and attracted riders from literally around the world. Now in our 13th year, this version shall be no different. Feeling lucky??

This is the longest one! LIMITED TO 50 RIDERS! Up to 115mi and potentially 12,000ft of vert. Famous for its vertical hike-a-bike sections, the multi-surface mele’ consists of county asphalt roads, trails, single track, technical challenges, a ridiculous amount of punchy steep climbs, rolling hills, a river, a creek, a cowboy bar and some creative shenanigan’s thrown in for good times.

This forecast shows the course from Boulder Cobbler 12.0 (2025). We'll update this page when the route becomes available.
