Yeah, I know that Johnny Gray officially holds the WR in the 600, but I'm wondering who you think would hold it if the race were run more often. Would it be a 400m runner stepping up or an 800m runner stepping down?
Here's the official list of the fastest 600m times ever run:
1:12.81 Johnny Gray
1:13.49 Joseph Mutua Mwengi
1:13.80 Earl Jones
1:14.15 David Mack
Johnny Gray had personal bests of 46.3 and 1:42.60. I have to think that Juantorena could have beaten Gray's 600 time considering his personal bests of 44.26 and 1:43.44.
