Plan Description

A customized plan to get you to the finish line of a hilly or mountainous 100 miler and run your best race!

I am a certified running and ultrarunning coach and an experienced mountain and ultra runner. I have completed UTMB 3x (28 hours, 72nd, top 3 American man), Bighorn (9th in 2022), Tor des Geants (2nd American), Cruel Jewel (8th in 2021), Hellbender 3x (2nd and 3rd place), and many more. I've successfully coached dozens of athletes for ultras including UTMB, Grindstone, Vermont, Rio del Lago, Val d'Aran, Bryce, Zion, and Kosziusko

This plan is mileage-based and assumes baseline experience with running ~50 miles / 80km per week and comfort with running trails and mountains. Training volume peaks at ~80 miles per week.

This plan includes:
- Daily workout type, mileage, and intensity levels
- Recommended type of terrain and vertical
- Specifics workouts (intervals, hill intervals, tempo runs, strides, etc.) targeted to performing your best in a mountain 100
- Weekly notes on the training intent and goals for that week
- An intermediate race / event / time trial at 13 weeks (with the option to skip this)
- Recommendations on when to include strength workouts and a set of recommended exercises
