Long ago, a 22-year old amateur named Bob Roll set his sights on a race coming to his home turf—a race up Mt. Diablo. Bob knew this would be his race. He had trained up the mountain’s Northgate Road every other day. Race day came and Bobke assaulted the mountain like a man possessed, beating out the pro favorites and taking a surprise victory in the 1983 Mount Diablo Hill Climb.
