Ready to Train for Your 100K Trail Ultra? Let’s Get to Work.
This structured training plan is built for intermediate runners preparing for the unique demands of a 100K trail race. Whether you're stepping up from a 50K or building toward longer goals, this plan is designed to develop the strength, stamina, and mental focus needed to run strong from start to finish.
You’ll follow a clear progression of long runs, back-to-back training days, and terrain-specific workouts—each one crafted to reflect the physical and mental challenges of a 100K. All sessions are compatible with Garmin, COROS, Suunto, and Apple Watch, so your plan goes wherever the trail takes you.
Included is a practical nutrition guide to help you fuel your training and long efforts effectively—essential for maintaining steady energy across the full distance. You’ll also dial in race-day strategies, test gear and fueling systems, and condition both body and mind for extended time on feet and the varied terrain of a true ultra.
If you’re committed to showing up prepared, this plan will help you build the endurance, confidence, and durability to take on your 100K goal—strong, focused, and ready.
