This plan is designed for the demands of a challenging 100-kilometer mountain race. The plan begins with specific hill sprints to build strength and durability before transitioning to 10 weeks of muscular endurance. The muscular endurance workouts are crucial to ensure your legs are ready for the demands of climbing and descending in the race. You begin the plan with two rest days but work into six days of running. In the later part of the plan, you will start the functional runner routine that focuses on mobility, range of motion and specific strength for runners.

Along with these key workouts, the weekends are designed with a gradual progression of mileage and elevation gain and descent based on the elevation profile of the race. There are also notes on incorporating night running, pole use and mandatory kit. This plan follows the traditional four week cycle of a three week build to one consolidation week to absorb the training. The peak week tops out with a 41-mile (66km) week with over 13,000 ft (4000m) of elevation gain and descent. The plan culminates in a two-week taper to get you well rested for the big day.
