From the man himself. I know it's been debated a lot on here in the past so thought it might be interesting. He also says he can run 1:48 for 800m and that he runs over 100mpw and runs twice a day, everyday.
This is while training for the 5/10k but the Ethiopians are famous for doing loads of sprints and strides so it's not as if he never practices sprinting.
400 PB of 49 and he ye can run within 3 seconds of that at the end of a 5k/10k race. Guy is a fricken machine.
