100 MILE ULTRAMARATHON TRAINING PLAN | 24 WEEKS | INTERMEDIATE
A complete 24-week build for a 100 Mile. Trail or road, flat or mountain - the plan adapts to your course instead of assuming one.
WHO THIS PLAN IS FOR
You've finished at least one 50 miler or 100K. This plan is built to get you to the finish line, not to a podium
You're currently running 6-8 hours a week consistently and a 2:30 long run feels comfortable
You can commit 5-16 hours a week, peaking at a 5:45 long run with a 3:15 run the next day
A GPS watch with heart rate, and a gym or a set of dumbbells
WHAT'S INCLUDED
24 weeks across five blocks: Foundation, Build, Peak and Taper, with three build weeks followed by one recovery week
Peak weeks of about 15.8 hours
Every run is a structured workout targeting a percentage of your threshold heart rate, so it syncs straight to your watch and paces itself - with an RPE cue in every description if you'd rather run on feel
A Week 1 field test that sets your personal zones, so the plan is calibrated to you rather than to a formula
2 strength sessions a week in 4 phases: foundation, max strength, downhill durability, then maintenance through the taper
A terrain fork built into the weekly structure - specific guidance for a flat, runnable course and for a mountain course with real climbing
Ultra-specific sessions:
Uphill VO2 repeats and threshold intervals
Steady-state race-effort work
Power hiking practice
Downhill durability work
Back-to-back weekend long runs
Night runs with full lighting kit
A full race-day dress rehearsal
Weekly notes covering the things that actually decide a 100 Mile:
Fueling and gut training to 60 to 90 g of carbs an hour
Pacing and the first-hour trap
Power hiking technique
Aid station efficiency
Shoe and kit selection
Handling the bad patch
Night running, sleep and foot care
Crew and pacer briefing
Heat and altitude
Taper, race week and a full execution plan
Post-race recovery
COMMUNICATION
This plan is self-guided. Every workout explains what to do and why, and the weekly notes handle strategy. Start with the Week 1 note, then do the Week 1 field test to set your zones.
EQUIPMENT
GPS watch with heart rate that syncs to TrainingPeaks (a chest strap is recommended)
Trails, hills, or a treadmill that reaches 10-15% incline, so the plan works for flatlanders
Gym access, or dumbbells or kettlebells, a box or bench and a resistance band
Race kit: a vest holding 2 litres, and the fuel you'll train with, building toward 60 to 90 g of carbs an hour
Headlamp plus a backup light, and a warm layer for the night
GOOD TO KNOW
Workouts are prescribed in time, not distance, because an hour on technical trail and an hour on pavement are different training sessions. Mileage shown is an estimate. Check your race's athlete guide for the current course, cutoffs and mandatory gear.
