Lots of climbing, Walden Ridge, Mt. Larry, into Windrock, up 116 and then a couple more miles to the peak in Frozen Head before descending into the campground. Spent the night and then back to car. Battery on GPS died with about 5 mles to go. Also did a couple miles in the morning before remembering to start the GPS. True total close to 80 miles and 7.5 hours of pedaling
