Hmm, off the top of my head:
9.79* the 30 for 30 from ESPN on the 1988 100m
I've seen parts of the Fred Lebow one and it was great
The CBC Nature of Things Perfect Runner is really good too until the author runs the Death Race.
I'm waiting for someone to do a great Kenya versus Ethiopia movie.
Thanks, Nev! One of our sports chiros, Dr. Larry Bell, was featured in The Perfect Runner. I liked the Death Race stuff because I've done the race but it definitely wasn't the best part of the documentary.
A much better Death Race film!
Also, there's the semi-doc of the Haile G story made by Disney called Endurance, but judging by the trailer, you'll want to limit your sugar intake that day.
