The beginner plans are designed for runners with some experience under their belts and ideally for those who have completed a full marathon. This means that they are familiar with the dedication needed to train consistently and have experience finding a balance between running and the stresses of daily life. The plan is 20 weeks long, so some prior base fitness is required. If you've been running for 3-4 days per week for more than six weeks you should be able to follow the plan as-is.

Intermediate plans are intended for runners who have completed an ultra distance before and/or have 2-4 years ultramarathon training experience and are trying to improve upon their time or placing from previous years. The plans are intended for runners that have some experience doing interval work and back-to-back longer runs. If you are looking to add more structure and guidance to your training, these plans are for you. If you are new to ultrarunning, or have over 5 years experience training for ultramarathons, the Beginner or Advanced plans will be a better fit for you.

Advanced plans are intended for runners that have more than 4 years training experience and are looking to maximize their performance. The plans are intended for runners that have more than 2 years experience doing interval work and back-to-back long runs. If you are looking to make the most out of your training, don’t mind pushing the envelope, have had some type of coaching or guidance before, then these plans are for you. If you have less than 4 years of ultramarathon specific training or do not have experience with interval work, the Intermediate or Beginner plans will be a better fit for you.
