This plan assumes an athlete that has advanced experience with running endurance events. Examples could be a history of ultrarunning events, long milage training blocks, or competitive distance racing. Athletes using this plan are likely to be targeting a competitive performance at the 50 mile distance. This plan targets a 50 mile race with approximately 2,000-5,000 ft of gain, such as, but not limited to, Ice Age Trail, JFK, Dead Horse, Dances With Dirt, Mohican, Marquette, or Indiana. This plan will start with weekly milage of 34 miles per week across six days of training per week, with an 10 mile first long run. The plan will top out with a 68 mile week and seven days per week of training, two focused workouts per week, and a 24 mile long run. This plan includes an alternate set of weeks to allow for a practice/tuneup race in the latter half of the plan. Each fourth week is a scheduled recovery week with a reduced workload. This plan assumes access to trails, with reasonably rolling terrain.
