I mean Henry Rono in his prime. I see there are some recent interviews with him on YouTube. It would be great to see any footage from his legendary 1978 season. But then I believe those World Records he set then were in minor college dual meets. There is a hilarious story from the Cal coach who saw Rono use a long distance race to do interval training. At one point Rono started down the front stretch doing the sprint part of his interval. At the same time a Cal long jumper was taking off on the runway for his jump. The coach said Rono was outrunning the long jumper.
In any case, it would be cool to see any footage of Rono from the late 70s to the early 80s. There used to be a 78'clip on YouTube of Rono running a 1500 against Ovett with Ovett outkicking Rono, but thats been deleted. I remember it was fascinating just watching Rono's running form.
