white lightning said:I really belive that for him to break MJ's 400 Meter World Record, he will need to vastly improve his 200 meter times. He needs to be around a 20.00 flat in the deuce to have the best chance to beat 43.18! I think he can do it but I don't know if he will approach that this season.
To be honest I dont think he will need to be at 20 flat in thee 200 (although he can) to break the world record. Speed endurance is odd. For example, Kenteris ran 10.15 in the 100 in 2001, and 20.03 into a .7 m/s headwind. In 2002, he ran a 10.44 100 and a 19.85 sec 200 into a .6 m/s headwind. Speed endurance is the key to winning, and 200m splits dont matteer that much. Just because MJ was a good 200m runner doesnt mean Wariner has to be.
Also this data suggests speed endurance is the best factor in 100 to 400m sprints. Only the first 40 meters are strength.
