@KC, I went to Luke's Locker in Dallas before i started and made sure and had proper shoes. I also have a trainer (my brother) who is very strict with his regimen. I've deviated a couple of times and he yells and says this and that will happen and he's always right, so I pretty much follow what he says. He's a triathlete and has been running marathons for almost 20 years. Anyway I'm sure he will make sure i do all long, short, tempo, kill-ya runs that I have to do.
