Zinn Gravel Fondo - 2026

The Zinn Fondo* returns this year as a gravel ride on the summer solstice. This year it will start and finish at the Zinn Cycles shop in Louisville. Riders can choose one of three 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. 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 turning left 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.
