The perfect plan for the experienced trail runner looking to take things to the next level! This 12 week plan assumes an athlete that has intermediate experience with running and hills. Examples could be recent experience in the half marathon or 25k distance and will train an athlete to run a trail marathon or approximately 26 miles. This plan will focus on training for the distance and climbing needed for completion; speed and high performance is not a main focus of this plan. This plan will start with weekly milage of 42 miles per week across five days of training per week, with an 8 mile first long run. The plan will top out with 60 miles per week and six days per week of training, with a 20 mile long run. This plan assumes access to trails that offer rolling or hilly terrain.
