RE: Which Sports Requires the Most Discipline?

I know that running really surprised me with how much discipline is required and I was talking to a friend of mine that had video of Kenyans doing 3minute kms regularly and that just surprised the heck out of me because I was at that point seriously impressed if I ever got close to 5mins. There is a lot to it and it is definitely more involved than "just run that way as fast as you can." You have to find a pace and also it is a massive mental game. While playing other sports growing up you were motivated by scoring a goal and were able to dig deep but when you are just running the only thing that you want to do is stop running.
