Plan Description

100-200-Mile Ultra & Multi-Day Endurance Plan — 15 Weeks for the Ultimate Challenge

This advanced training plan is built for the world’s toughest events: Up to 200-mile races, multi-day stage ultras, or expedition-style challenges like Marathon des Sables or Badwater 135. Over 15 weeks, you’ll develop the physical durability, mental resilience, and strategic preparation needed to succeed in these extreme endurance environments.

What’s included:

5–6 runs per week with progressive back-to-back long days

Strength and conditioning twice per week

Recovery and adaptation weeks to maintain long-term consistency


Who is it for?

Experienced ultra athletes with multiple 50K+ finishes

Runners stepping into multi-day or up 200 mile endurance events

Athletes aiming for iconic events like MDS, UTMB-series 200s, or Badwater

This plan will help you not just survive, but thrive in extreme endurance races — with a smart, structured approach that balances training load and recovery.
