Yeah, I think you have a point there...at first, I was going to reply to that message by saying "Well, I run in my martial arts classes", but I realized a second later that we usually run on mats (hard mats that suck for breaking your fall, but they're easier on your feet).
Thanks for your advice bro, I'll try to slowly progress.
