The 7:30 Mine Trail is a gorgeous jaunt above the historic town of Silver Plume, CO. Steeped in Colorado’s rich mining history you pass remnants of bygone days as you make your way up the climb culminating in an up close and personal look at a mine shaft entrance. The mountain views are breathtaking as you run up and the grade is perfect for bombing back down to town!

This is an awesome route for both Front Range locals looking for a little altitude training, and visitors looking for a historic run. Enjoy the views and the history!

Big Rock Ridge is one of the most recognizable features in Marin County, and has sustained views on all sides for several miles. Starting from the Big Rock trailhead on Lucas Valley Road, climb immediately up to the top of the ridge, then follow fire roads generally down the ridge until reaching the Ponti ridge mountain bike trail. Take a left and follow all the way down to the Terra Linda-Ignacio bike path for the last half mile to the parking lot.
