Welcome to my 12 week half marathon plan for intermediate runners. This plan will target the runner who has some experience and wants to improve on their prior race times. The 12 week program includes 5 days of running, one day of rest, and one day of crosstraining. The mileage starts at 24 miles per week and works up to 36 miles per week. The goal of this program is to finish a half marathon in 2 hours.
