Curly bars, flat bars, knobby tires or skinny tires… Gnarshall Mesa rips! It’s the first ride of 2026 and we are going hit one of our favorite trails in Marshall Mesa for a lap around Dirty Bismark and finish at Illegal Pete’s in South Boulder for salty margs and big burritos.
We will be rolling at 5:30pm from Illegal Pete’s for a 20-mile loop. There will be a neutral roll out to the trailhead where riders can ride at their own pace between regroups. We love this route as it is a mixed bag of terrain and has a lot of singletrack with beautiful views of the Flatirons in Boulder. We will have two regroups, one at the Coalton Trailhead off McCaslin and the other at the Marshall Mesa Trailhead Parking Lot before heading back together.
This route does have some technical riding involved but we have updated the route to take out some of the super chunky stuff on the backside. Bring lights, layers, flat kit, and everything you need to finish the ride. Stay at Illegal Pete’s after for food and drinks, and all riders will be getting 2-50% off drink tickets who attend.
Please familiarize yourself with the route! We will have a couple spots to regroup, however, this is NOT a ‘no drop’ ride. This ride will require technical bike handling skills and may not be suitable for beginner riders. We will have a leader to guide the group and maintain a moderate pace, but will not have specific sweeps.
