The number of championship races I've seen is definitely over 1000 (thanks to youtube). I've been a competitive runner since 1972 and have done a lot of digging on youtube over the last ten years. I doubt that there is more than 30% of championship races on youtube that I haven't seen. I'm talking even at the level of AAU, Jamaican "champs", NBN, various state champs, etc..
This was one of the greats. The storyline on Sydney Mc alone was epic, not to mention VT, USC, etc..
