If you’re ready to run your first marathon, this plan is for you. It is geared for those who have run for at least a year, and have been running an average of 20 miles per week for the last three months. Each week features four days of short runs, a long run, and two days of rest. The plan also includes Yasso 800s to help ease you into speedwork, and marathon-pace runs to help you get used to running at the pace you'd like to target in the race. The mileage starts with 25 miles per week and peaks at 42 miles per week. Each day, along with your workouts, you’ll also get tips on training, nutrition, and injury prevention from the Runner’s World experts.
