Ready to Train for Your First 100-Mile Trail Ultra? Let’s Get to Work.
This structured training plan is built for intermediate runners ready to take on the immense challenge of a 100-mile trail race. Whether you're stepping up from a 50K or 100K, or going all-in on your first hundred, this plan is designed to build the strength, stamina, and mental toughness needed to reach the finish line.
You’ll follow a clear progression of long runs, back-to-back training days, power hike sessions, and terrain-specific workouts—each one crafted to simulate the real demands of a 100-miler. All sessions are compatible with Garmin, COROS, Suunto, and Apple Watch, so the structure stays with you no matter where the trail leads.
Included is a practical nutrition guide to help you fuel your training and long efforts properly—essential for staying steady through the later miles. You'll also develop race-day strategies, test gear and fueling, and condition your body and mind for extended time on feet, overnight movement, and the highs and lows of a true ultra.
If you're committed to crossing that 100-mile finish line—whether it's your first buckle or a dream years in the making—this plan will help you build the endurance, confidence, and resilience to get there.
