There's a fair amount of stuff on the internet about recovery time per se.
The trouble is, there's doesn't seem to be any details about the recovery times of individual athletes. I've drawn a complete blank even after typing in names such as Linford Christie, Kriss Akabusi, Sebastian Coe, Steve Cram and Roger Bannister.
I don't know what else to suggest. Perhaps they don't want to disclose this information.
