I'm almost halfway through my third half marathon training and I am really happy with the results. Since this time my goal isn't just to finish, it is really interesting to see how specific kinds of training can actually produce results (for me, increasing pace).
In addition to being increasingly confident that I'll be able to do the half-marathon in under 2 hours, I have seen my body change in ways that exercise has never done before.
My body is actually stronger - stronger legs produce faster paces, better aerobic capacity helps endurance, and eating the right fuel gives you the energy you need to do the things you want to.
I haven't really lost any weight (that's not a goal), but things that used to jiggle are now firm. Jumping up and down in cardio class this week I thought as I looked in the mirror, "huh, my thighs are staying right where they were." In fact, I'm not just stronger, I have actual defined muscles.
So, thank you Hal Higdon and lean protein!
