Fridays are rest days leading to the weekend workouts. Tuesdays and Thursdays offer short and easy runs, bracketing the sorta-long runs on Wednesdays, the middle of the week.

Mondays are for cross-training serving as recovery from the weekend workouts. Half Intermediate 1 features steady running, long and short. They are part of the logical progression upward from Novice through Intermediate to Advanced for the half marathon distance. These two intermediate schedules exist in a parallel universe, the same level of difficulty, just slightly different approaches to training. Previously, there was only one, titled simply "Intermediate." Now there are two: "Intermediate 1" and "Intermediate 2." The difference is that Intermediate 1 is an endurance-based program Intermediate 2 is a speed-based program. Hal Higdon: Half Marathon Intermediate 1: With the publication of my recent book, Hal Higdon's Half Marathon Training, I created three new programs not only for the book, but interactive here through TrainingPeaks.
