Actually watched a tyson documentary this morning on the biography channel and they had they micky rooney on.

Was saying how early tyson used to run 6 miles a day more than any welterweight,, middleweight etc they had in the gym at the time.

Also showed how nervous mike got before a fight and how he had serious confidence issues and struggled to look someone in the eye when they were talking to him due to that.

He went from running 6miles a day to 1-2miles which is still pretty good though you do realise why mike was indeed the animal he was back in the mid/late 80s as he was almost superhuman!!
