pb 6.15 - training schedule half marathon - level 3 advanced

PDF · 1 Apr 2026

The document presents a 12‑week, Level 3 (advanced) half‑marathon training program created by Floris Gierman for extramilest LLC. It is intended for experienced, competitive runners—typically those aiming for age‑group awards—who have completed at least three months of a base‑building schedule (3‑10 hours per week). The plan starts at roughly 5 hours of running per week, builds to a peak of about 9 hours in week 10, and includes 5‑6 active days with occasional double‑workout days. The structure follows a repeating pattern of three “building” weeks followed by a “step‑back” (recovery) week; every fourth week (after the step‑back) a MAF test is performed on Sunday to gauge aerobic progress. Workouts are diversified: aerobic runs/walks, recovery runs below MAF, various speed‑work sessions (high‑intensity Wednesday workouts), and long runs that gradually extend to around two hours, typically scheduled for Sunday. The schedule emphasizes listening to the body, tapering with reduced volume and intensity during race week, and provides community support via Personal Best Facebook and Strava groups for questions and encouragement.
