The Ultimate Gravel Cycling Adventure Comes to Groveland, CA on Saturday, June 24th!

We had to move the date to June 24th due to the impact on the Stanislaus National Forest from recent storms. We apologize for any inconvenience.

The Groveland Grind is a Yosemite Area Adventure Ride on mixed terrain(pavement, broken pavement, dirt and gravel)on Yosemite National Park’s doorstep! Three amazing routes with amazing views to choose from- Ride the 48 miles Long route- The Rumble up to Trumbull(Peak), the 30 miles medium route or the 21 miles Short route through the majestic Stanislaus National Forest on historic sections of the original roads and railroads to Yosemite!

The event takes place at Yosemite Lakes RV Resort and Campground, 31191 Hardin Flat Rd., Groveland, CA, 5 miles from the entrance to Yosemite and next to the South Fork of the Tuolumne River! Groveland is just 2 to 3 hrs from San Jose/San Francisco/Santa Cruz/Sacramento and 1 to 2 hrs from the Central Valley.

The Groveland Grind supports the Groveland Trail Heads and their development of a mtn bike specific single-track trail system that is inclusive while promoting health(physical and mental), outdoor recreation, adventure and economic development throughout the Groveland area. We’re trying to raise $20K to receive a match of $20K from Sonora Area Foundation to build our next mtn bike trail in the Ferretti Trails trail system!
