yea Much of that running endurance is not going to carry over into fighting completely different Do lots of grappling sessions and pay attention to what Onganju said he always gives some excellent advice. If he is a beginner and the fight is 4 months away.. you guys better be training at least 5 hours a day. say an hour weating and conditioning and 2 hours of grappling and 2 hours striking. Might seem extreme but training like that will help build your endurance in the ring. Also go back and read through the trainig section on this site lots of good stuff posted by myself, Onganju and others like Ironman to name one.
