80-mile 11,000 ft training at Mt. Hamilton for the Death Ride California. Don't make this mistake.. 

It's not for the faint at heart. Training for the annual Death Ride California, which could be the most brutal one day bike ride course in the world if you push yourself hard enough. We're training by climbing Mt. Hamilton two times from the base with a total of more than 80 miles & near 11, 000 ft in total elevation gain. One round trip to the Mt. Hamilton summit is a 40-mile loop with a total elevation gain of 5,500 feet.
