My training rides depart from my work place, Moccasin CA. We are near Yosimite. I have three rides to pick from but the one I can recall is 32 miles, 3500 elevation gain, short grades of 13-15%. We do it in less than two hours, usually averaging about 15.5 MPH. Ride number two is 2 miles of 15% grade. Ride #3 is 32 miles, 4500'. I have recently started riding, after a 15 hiatus. I lived in the Central Valley where flat riding was the only choice. I have to say that the elevation I deal with now has made me stronger than my younger years in the valley. We also have top notch MTB trails here, one is about 35 miles long combine fireroads and single track along a canal.
Saturday's ride was 96 miles, 8500'.
