Speaking to my dad today he relayed a great story.
My dad, a solid sprinter in his day (49mid in the quarter, 22.4 on the 220 straight away on cinder track in high school) was at a meet in Madison Square Garden in 1961 or 62.
This is what my dad told me:
Hayes was at the meet to run the 60yd dash.
Charlie Greene from Nebraska (who took bronze in 68 in the 100m) walked up to Hayes before the race and said ’ I know you’re fast but you’ll have to break the world record today to beat me’
Hayes went on to run 6.0 or 6.1 and broke the world record.
sometime later I believe he was the first to go sub 6.0 for the 60yd.
Wow! Your pops was fast back in 68. This reminds me of even Charlie Francis himself clocking a 10.1 (if I’m not mistaken) back in the stone age. (lol) J/k!!!
