So I'm going to do what I always tell other people, and start slow. If I do the full Couch-to-5k program in its entirety, I should be able to run a full 30 minutes in 9 weeks. There are 9 weeks left in this calendar year - how about I achieve a New Year's resolution before the new year begins?
And I'm not going to commit to anything larger than this right now, beyond those 9 weeks. I tend to set very high goals for myself, which I guess is a good thing (because at least I'm ambitious), but I inevitably fall short of them because my body's limitations cannot stretch that far that quickly. I know I can run 3 miles because ONE TIME I actually ran a full 6 miles, and I know I can get back there again.
