Oh man, I really admire you. Even in my best shape I could never run far OR fast! Your dedication is amazing. Seriously! I was starting to get nervous about this contest as well and then things finally started working better for me and my own goals.
I wish you the best of luck!
Yeah, it can certainly plateau at times. It's funny for like 30 years, I hated running, every jog in the army was pure torture and I would go one and one about how "I'm not built for running" or whatever. Then for some reason (a girl) I gave it a honest try and I've been really into it (on and off) for the last 5 years, but I do have some long term running goals.
Ahhhh.. a GIRL. Now I see. I guess I need to meet new people who are more inspired and motivated to exercise! :)
