Plan Description

Mountain Running

100 Mile Mountain Ultra Peak Plan

"It's not what you get from your training, it's what you become from your training"

Built for athletes who are looking to tackle an ultra in mountainous terrain. The Mountain ultra plan takes a major focus on climbing and descending to prepare you for the demands of a long race over tough terrain. This plan is specifically built to only deliver the final 14 weeks of training, or the peak portions and build up of your training.
Created by USATF Level 2 Endurance Coach and Athlete Andrew Simmons. This plan is built on the knowledge gained from years of coaching, and 10+ years as an amateur elite runner (36+ Marathon or longer distance race finishes). Andrew has a passion for coaching that is evident in not only his personal performances but in the success his athletes see on race day.

This plan is designed to give you only the meat of the training. This is a 14 weeks plan these dives directly into higher mileage training, and still includes a 50K and 50 mile/100km race in the build up. This not a plan to use if you're looking to start from square one. This plan is HR and Pace based and utilizes a flat time estimation of 10:00/ mile.

All workouts are HR based and will adjust as your zones are adjusted in each fit test. This plan focuses heavily on climbing and also includes specific endurance workouts so you can test not only race strategy but your race day nutrition and hydration plans. The long runs live on the weekends. This plan can be set to start on any Monday and will run for 14 Weeks.

Before you jump in you should be able to complete:
  • A previous 50K or 50M
  • Be confident with strength training
  • Nutrition and Hydration strategies for long distance races
