Fulghum is known to wear a costume and cape while riding his bike around town. He says summiting the 13,796-foot (4,205-meter) mountain was tough, but was a part of his effort to get "the most out of life with a physical challenge."
The 80-mile (129-kilometer) upward ride went through sand and gravel. Fulghum started before the sun came up Saturday and finished Sunday afternoon.
