Rupp 4x400 workout -- 51 seconds each. How much rest/recovery do you think he had?

Did mo also do this workout? What were his splits? Recovery?? I don't know. More to your point, I'm sure they focused on race pace running in many workouts the weeks leading up to the race. Sometimes a week out from a race you want a hard fast stimulus to shake up your body. Basically saying it's time to go fast now. Vigil prescribes an all out mile TT a week out. Salazar does this. Pretty standard stuff for a week out speed session. 51s is smokin!

If I had to venture a guess he would have between 4 and 8 minutes rest. It's an awesome way to work on a kick. I run this workout a lot (800-1500 guy) and after the second rep, you're feeling it and will struggle to maintain your form at high speeds. Smart workout IMO.

If that's true, the speed was there for the workout, but maybe sapped his legs for the kick in the race. He doesn't seem to recover very quickly from hard efforts. What he did have in the race was the ability to maintain 64-65 pace. Or maybe the heat was the entire explanation for why he had no kick and he will run very well in Europe.
