This 12 week training plan is geared toward the somewhat experienced beginner and intermediate ultra runner who has been running consistently for 4-5 years and has done at least one marathon distance event. This 50 mile plan has an ideal balance between quality training and recovery to promote the best physiological adaptation and get you to the line in great shape. The athlete should be able to run 12 miles as a long run as the program begins.

This plan was developed by Bob Seebohar, 2-time Leadville 100 run finisher (and a 2009 Leadman finisher), endurance coach, strength coach, exercise physiologist and sport dietitian.
