Max Woodbury, 41, a C6 quadriplegic, took part in the Hood to Coast Relay race using a handcycle. The annual event begins on Mount Hood in Oregon’s Cascade Range and ends at Seaside, Ore., a distance of about 200 miles. Teams consist of 12 runners who run three legs each — averaging about 5.5 miles per leg — and travel in two vans when not running. The race is continuous, with no regular sleep or meals, just occasional naps or snacks. For a few elite runners, the race is serious business. But for most participants, as many as 15,000, the race and the ending party on the beach is a fun event rather than a competition.
