Half Marathon | 8-Week Intermediate Performance Plan
Improving your performance over 21.1km requires a shift from general running to training with a specific purpose. This 8-week plan is for intermediate runners who want a professional structure to reach a new personal best. It provides a clear path to build the stamina and pace needed for the distance. By following a methodical system, you can balance your preparation with a demanding career, ensuring every session counts toward race day success.

Success in a shorter timeframe is built on consistency. This plan focuses on four purposeful runs per week, allowing for high-quality work followed by adequate recovery. You will move through a structured build that increases your ability to hold a faster pace for longer. This framework removes the stress of second-guessing your training, giving you the confidence that your preparation is grounded in sound principles. Every hour you spend training builds the resilience needed for a successful race.
