I'm going to start officiating football next year. Im already licensed to umpire baseball so the sports officiating world isn't new to me. However I need to start some kind of running program to build endurance. I already HIIT some (although I have been lax here lately, Im having some problems that seems to be sucking the life right out of me) and I need to get going, next fall will be here before I know it.
Any ideas?
