The Zinn Fondo (largely) mountain gravel and road ride will start and finish at the Zinn Cycles shop in Louisville. Riders can choose one of four loops of approximately 60km, 85km, and 100km in length. There will be a ride leader for each loop. All three loops will be primarily on bike paths and dirt roads and we will have a road only route for those who don't like gravel. The “Corto” (short loop) goes up Chapman Dr. and down Flagstaff Rd. The “Medio” (medium loop) goes up to Gold Hill via Fourmile Canyon Dr. and Gold Run Dr. and returns via Sunshine Canyon Dr. The “Lungo” (long loop) follows the Medio loop with the addition of a left turn at Salina to continue along Fourmile Creek to Pennsylvania Gulch and up Switzerland Trail to Gold Hill Rd., rejoining the Medio loop at the Gold Hill Store.The Zinn Fondo is also an official training ride for the Ride Collective events, Copper Triangle, Enchanted Circle, Tour of the Moon, and Tour De Vineyards

*The Zinn Fondo ride started 38 years ago, in 1988, on Lennard Zinn’s 30th birthday. The idea was to ride in the mountains from dawn to dusk (or later!), enjoying companionship and great views with good friends. Many routes were used. The original route, repeated, a few times was the “Grand Loop” from Boulder, comprising 369km (229 miles), 19,000 feet of climbing, and two crossings of the Continental Divide via Estes Park, Trail Ridge Rd., Granby, Winter Park, Berthoud Pass, Idaho Springs, Peak to Peak Highway, and Nederland, finishing back in Boulder.
Zinn Fondo distances and elevation gain have moderated now, as Lennard is turning 68 and has a heart arrhythmia and an e-bike. What hasn't changed is enjoying a friendly ride in the mountains with good people. This time, the course isn't changing, either. In the interest of keeping a known, wonderful, favorite route of Lennard's that our friends can count on and put on their calendars, it makes sense to keep it the same for now. We hope you'll join us!
