3 so far this year, it is way to hot in the summer to ride during the afternoon in Miami. I am doing a 120 mile ride in sept. in CO. That should be a spectacular ride.
Riding from downtown Ft. Collins up to Trailridge, 7000ft of climbing tops out at 12,500 ft. Best part is that it will be the day after climbing Mt Evans 22 miles with 8000 ft of vertical, tops out at 14,000 ft. The two highest paved roads in the U.S.
