Md. Man In Wheelchair To Take Part In D.C. MarathonTom Chepurko didn't bargain on participating in any marathons anytime soon. It wasn't just that the 53-year-old Odenton resident hadn't trained for years. Chepurko largely depends on a wheelchair for mobility. He was injured in a skydiving accident in 1981 that caused partial paralysis from the waist down.
