Edwin Moses documentary '13 Steps' shows how clearing the hurdles was the easy part for a track icon

Not long after Edwin Moses figured out how to attack the solution to track's ultimate math problem, he transformed himself into the best hurdler in history.

That, in turn, gave the engineer-turned-Olympic champion the platform to go after more difficult issues that, even today, more than 40 years later, nobody has totally untangled.

The title to a new documentary on Moses, “13 Steps,” pays homage to the then-revolutionary number of strides the track star took between the 10 barriers in the notoriously painful 400-meter hurdles — a race where he lined up 122 straight times over a span of 9 years, 9 months and 9 days without getting beat.

“Everyone's angry about something, but what can you do and what are you going to do?” Moses says in the movie, reflecting on the larger-than-sports role he assumed after becoming one of track's brightest lights in the 1970s and '80s.
