do fighters really need to go running?

[racer59]

Yes they do. Long slow runs. You need two things. Wind and legs. Long runs help with both.

Guys like Toney didn't. But that's only because they were masters at the hardest thing to get used to in the ring. Staying very loose and relaxed.

Im pretty sure I seen Wlad running.

Does anyone know if Vitali stopped running being old, big and having a bum knee?

What about Valuev, how much running did he do? He was over 300 pounds, that has to suck for his knees.
