Har, no I can't use food as motivation, gotta cut back and be a good boy, I am practicing control over the food and doing well with that right now. That's interesting about entering a race. I don't think that's something I'd want to do, but maybe I could have some other target like that which I'd need to get good for
Yeah, I figure food motivation only works when you weigh 108 pounds and can't seem to put on weight.
As for races, you don't need to be a fast runner to go in them (if that's what you're worried about). My dad enters two races a year, 5k, just to get keep himself going out there. He does 5k in about 30-35 minutes, which isn't bad for an "old guy" but he doesn't care about how fast he goes. Lots of people who enter are not fast at ALL, they just use races as motivation and like to get a t-shirt.
My former running "coach" convinced me to go into a race fairly early on and it was a great idea, because it was good motivation, and I've found races to be a bit addictive. It's my upcoming races and goals that keep me going out there even though it's freezing cold and I'd rather be lying in bed in front of my heater.
