Mountain Running

100km to 100 Mile Mountain Ultra 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. Some workouts are adapted for athletes who do not live near extreme or mountainous terrain.

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 the tools you need to succeed as an intermediate or advanced athlete. Unless you’ve completed multiple 100km races or have a long history with ultra distance training; this plan may be too much. Consider your previous training when selecting this plan. This is a 24 week plan that dives directly into higher mileage training, and includes a 50K and 50 mile/100km race in the build up. 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 24 Weeks.

Before you jump in you should be able to complete:
  • Significant experience with 50M-100M racing experience.
  • Be confident with strength training
  • Nutrition and Hydration strategies for long distance races

    Long Run

    This is your best chance to start training for your course. If you're racing a 100 miler in the mountains it's best to find a challenging course and build in longer and longer sections of climbs into your long run.

    Variation is always good too! Make sure you're trying out new nutrition methods and fuels until you find the right mix!

    Sample Day 6

    Recovery Long Run

    Easy aerobic recovery run. Might not seem too bad to start but in coming weeks these runs will feel like the shortest run of the week!
