Gnar Runners

Born from the ranks of the Fort Collins trail running community, Gnar Runners events are designed to promote enthusiasm and passion for the sport of mountain, trail and ultrarunning.

Whether you are leading the charge at the front of the field, playing host in the middle of the pack or chasing course cut-offs, our dirt-based races are geared towards helping you achieve your off-road running goals in stunning outdoor environments.

While we seek to create challenging running lines on as much gnar-filled terrain as we can reasonably find, we also guarantee impeccably marked and measured courses, bountiful aid stations, and a post-race atmosphere to remember.

Be gnarful out there!

VFuel to Provide Gel for the 2014 Quad Rock Trail Races

We are happy to announce that VFuel Endurance will supply gel for the 2014 Quad Rock Trail Races.

VFuel Endurance GelAid stations will be stocked with all of the current VFuel flavors: Peach Cobbler, Vanilla, Fudge Brownie, Cool Citrus, and Maple Bacon.

Gel pack samples will be included in the race packets but to cut down on waste and to ensure that we have enough gel for all runners, aid stations will only have bulk containers of gel. Runners will need to bring their own gel flasks to refill or ‘shoot’ gels at the aid stations.

VFuel was founded by local ultra runners from Estes Park, CO. The VFuel formula was developed and tested right in our back yard on the trails of Rocky Mountain National Park. As the first true endurance gel, VFuel is made for tough mountain courses exactly like Quad Rock.

Superior recovery, ease of digestibility, and delicious flavors intended to be consumed for hours and hours, are just a few of the benefits of VFuel Endurance Gel.

We encourage Quad Rock participants to try and train with VFuel before race day. Order online from and enter coupon code QuadRock14 for a 20% discount.
