I have an MMA match in two months. I've never fought MMA. I have fought grappling tournaments and 1 kickboxing match. My gas stayed with me through all of that without running. However I want to guarantee my gas tank in this MMA match so it's not even a question in my mind. Is a 10 kilometer run daily or every other day good enough preparation? (on top of regular training sessions of course). It's amatuer so it is only three 3min rounds I hate running, and I think leaving my comfort zone will do wonders for my cardio and confidence.
