Cerebral palsy meant Andy Sullman struggled to tie his shoes, cut his food and even lift his head up. But all of that changed when Sullman began running a year ago. Now, the 18-year-old is preparing to run his first marathon this weekend. He doesn’t know how he’ll fair against the other runners, but at long last he’s confident that he’ll be able to tie his own shoes before the race, reports the Houston Chronicle.
