10-Week Half Marathon Prep: Threshold & Race Pace Focus

This 10-week intermediate to advanced training plan is designed for runners ready to push beyond steady mileage and start racing faster.

This program blends time-based and mileage-based training to keep your body progressing efficiently while managing fatigue — ideal for runners who already have a strong aerobic foundation and are ready to sharpen race-specific fitness.

You’ll develop the ability to hold threshold and race pace longer, run stronger in the final miles, and improve both speed and endurance through structured interval work, progressive long runs, and targeted recovery.

What to Expect:

5–6 training days per week

Threshold intervals, tempo runs, and progressive long runs

Easy aerobic sessions to build durability

Strategic taper weeks for recovery and adaptation

Workouts built to sync automatically with your device via TrainingPeaks

Who It’s For:
Intermediate to advanced runners (currently 25-45 miles per week) aiming to run a faster, more confident half marathon — whether you’re chasing a new PR or aiming to sustain race pace with more control and less fatigue. Also for runners who have race experience and their individual pacing numbers to work off of.

Goal:
Develop superior aerobic efficiency, raise your lactate threshold, and finish your race strong at or above your goal pace.
