Hal Higdon 10-K--Intermediate: This is the Intermediate 10-K Training Program, for runners who want to improve their performances. What defines an Intermediate runner? You should be running five to six times a week, averaging 15-25 miles weekly training. You probably also should have run a half dozen or more races at distances between the 5-K and the Half-Marathon. With that as background, you now need a somewhat more sophisticated schedule to improve. Each day, I will send you an email telling you what to run and also offering tips about training.
