Stephen Wampler can’t walk, but that’s not stopping the 41-year-old with cerebral palsy from climbing El Capitan, a towering 3,000 foot granite formation at Yosemite National Park.

A tough climb for even those in the best of shape, Wampler is training to scale the peak later this summer one pull-up at a time. Arriving four to six inches higher with each movement, he plans to climb 400 to 450 feet per day.

Wampler is relatively new to climbing, but was inspired to conquer El Capitan by two friends who have done so despite both having quadriplegia. If successful, Wampler is expected to be the first person with cerebral palsy to reach the summit.

About a year into his training, Wampler is well on his way to readiness for the climb, having recently scaled 2,500 feet on a practice run, reports The San Diego Union-Tribune. To read more click here.
