Hey Boxer Dude

Pro boxers in the run up to a fight will run each day, tending to favour longer, slower runs. They tend not to work in too many sprints, but a few guys I know have started using conditioning coaches who opt for big powerful interval runs to work on anaerobic fitness.

In the amateurs, we tend to request that the boxers do longer, slower runs in pre and early season (to build stamina and work aerobically), no more than 4 to 5 miles. On an ongoing basis throughout the season, we'd expect a 2 or 3 miles (good pace) on non-gym nights (as Scrap said), and a session of sprint work outside the gym during gym nights. We tend to insist on them taking the weekend off, allowing decent recovery to take place.

Running is so, so important, but it shouldn't be overdone otherwise burn out will be a problem.

Cheers man
