The Novice 1 program is designed for beginning runners who want to prepare for their first 13.1-mile race. If you have run several half or full marathons before, you might want to take a look at the Novice 2 half marathon program, which is designed for more experienced runner. First-timer? This is the program for you. In choosing the half marathon, you are choosing the most popular race distance in America. According to Running USA, 2 million runners did a half marathon last year. That is four times the number of the half million who ran full marathons. If your long-range goal is 26.2 miles, a 13.1 mile race offers a good starting point. Or if 13.1 is more than enough race mileage with no desires to go 26.2 (at least for now), you have discovered one of our most gentle training programs. If you can handle the 3-to-4-mile runs prescribed in Week 1, this program will get you ready to run 13.1 week at the end of 12 weeks.
