This 16-week plan is designed for advanced runners preparing for a trail marathon. Ideal for athletes who already run 5-6 days per week, averaging at least 40-50 miles (65-80 km) per week. The program combines progressive long runs, hill workouts, fartleks and race-pace runs to build strength, endurance and trail-specific skills. The plan is flexible and can be modified to 5 running days per week by omitting the easy runs on Saturday or Thursday. It includes detailed guidance on how to adapt the plan to your needs and current fitness level.
