I did a little research, and the program was written by Bill Pierce. He originally had created a marathon training program called FIRST, which I understand is also very successful. He then cooperated with Runners World to create this 10 week half training program.
Some other reasons why I think it is a plan that can be successful:
- It's not alot of hassle. It is running three days a week - so relatively low mileage and reduces the risk of over-training or burnout... or better yet for busy Mom's making three runs work in a week is pretty do-able!
- The three runs that you do are specifically purposed to give you the most benefit. Speedwork makes you faster; tempo runs raise your lactate threshold, enabling you to hold a faster pace; and long runs increase endurance.
- Speed sessions vary between 400s, 800s, and 1600-meter repeats.
- Tempo runs build up from two miles to eight miles at faster than your normal pace, and faster than your targeted half-marathon pace.
- Long runs are done slightly slower than your targeted half-marathon pace but not as slow as you might typically run for a long run.
I created a training program page with the details of the plan; choosing your goal time, setting your target paces, and the actual 10 week schedule. I thought it might be nicer to have on a page without all of my above ramblings! Let me know if you find it as successful of a plan as I did or if you made adjustments for yourself that made it better for you!
