Rupp's workout reminded me of the thread about Geb's recent WR--could you run one 400 at his marathon pace for 104 days in a row? could you run 1 mile at his pace for 26 days in a row...
WR 5000m is 25 x 200m in about 30.33
So Rupp ran 4800m at 5000m WR pace with tempo-ish pace 200s in between.
I'm very impressed. I hope it translates for him. It'd be a shame for all this fitness not to add up to some fast wins in big races.
