He goes 1:50-1:50 in heats w no more than 5 mins between the end of the first and the start of the 2nd, and comes back 15 mins after the second one to run 1:53. I dont have a good sense of what this means for his 1500m fitness... is this a piece of cake for a guy with a 3:35 SB? Is this unheard of outside of Webb's 2007 workouts? Somewhere in between?
