This plan was designed for runners who are training for the Runner's World Half-Marathon in Bethlehem on October 21. It is ideal for beginners who have at least six months of experience running and who log an average of 15 to 20 miles per week. Each week includes three days of rest or cross training, and three to four days of running. Each week features a long run, which starts at 4 miles, builds gradually, and peaks at 10 miles. The plan features hill work to build your legs and lung strength, and to prepare you for the inclines and descents that you’ll face in the race. You’ll also do some gradually longer segments of running at race pace to build your fitness and give you the stamina you’ll need to finish 13.1 miles feeling strong. The program also includes notes on the Bethlehem course.
