Marathon | 14-Week Intermediate Performance Plan
Preparing for a marathon requires a shift from general fitness to structured preparation. For intermediate runners, the goal is to maintain a consistent pace over the full distance while balancing training with professional responsibilities. This 14-week program provides a professional framework to improve your endurance and speed. By removing unstructured miles and focusing on sessions with a clear objective, you ensure your training is both efficient and effective.

Success over 42.2km is built on methodical progression and adequate recovery. This plan replaces training uncertainty with a system targeting your specific race-day requirements. You will move through a structured build that increases your capacity to maintain speed for longer. This framework removes the decision load of planning, providing confidence that your preparation is grounded in sound principles. Every session contributes to your durability for race day.
