January 8th, I started a training program for running a half marathon. I started with the very beginning schedule, for people who do not consider themselves runners. For the first 5 weeks, I just walked! I've kept building up each week and now I am on week 12 and today I have to run 28 minutes and walk 2 minutes. Getting into an exercise program like this is great because you start off at an appropriate pace and don't overdo it. It lets your heart build strength so that you don't get tired so easily. I definitely recommend this schedule! After I finish this schedule, then I move up to the half-marathon schedule that lasts about 25 weeks. Check it out, even if you're not planning to run in a race!
