Plan Description
đ Chase Your Half Marathon PR â 12 Weeks, 5 Days a Week, One Peak Performance
Built for advanced runners with at least 3 years of long-distance running and a half marathon under their belt, this 12-week program is designed to maximize performance, precision, and race-day execution through five training sessions per week.
đââď¸ What Youâll Do: Start in the low 30s for weekly mileage and build to mid 40s. Each week includes two easy-effort runs, one distance-building long run, one interval or threshold workout to build fitness, and one progression run to experience different heart rate zones.
đ§ Train Smarter, Finish Stronger: Youâll get the most from this plan with a GPS watch to monitor distance, time, and pace. Many sessions are heart rate-guided for precision, so a chest strap monitor is recommended for the most accurate data.
đ Built for Progress, Backed by Results: This plan helped runners set a personal record at the 2025 NYC Half Marathon â and the feedback was overwhelmingly positive.
If youâre aiming for a breakthrough performance and ready to train with focus and discipline, this is the blueprint.
