Canyons 100 Mile Training Plan: 26 Weeks, Intermediate, Heart Rate
Prepare specifically for the Canyons 100 Mile with a structured 26-week heart rate training plan for established trail runners who want a strong performance. It develops threshold, climbing strength, downhill durability and race-specific endurance for the demands of the Canyons course.
The Race
161 km (100 mi), about 5,550 m (18,200 ft) of climbing and 6,700 m of descent, point to point from China Wall (Foresthill) to Auburn on the Western States Trail. 35 h cutoff; a Western States qualifier. Deep canyons of the American River: Devil's Thumb, Swinging Bridge, the Rucky Chucky river crossing and the K2 climb. Repeated 400-700 m canyon climbs and descents on singletrack and fire road, warm canyon bottoms and a cool night.
Who It Is For
You have finished a 100K or 100-mile race, run 5 times a week (7-8 h), and do regular 2.5 h long runs.
Your 26 Weeks
- Phases: Preparation week 1, Base weeks 2-10, Build weeks 11-17, Specific weeks 18-23, Taper weeks 24-25, race week 26.
- Weekly: 5 runs and 2 strength sessions, about 5.8 h rising to 14.3 h of running.
- Long runs: 2h00 to 6h30, with back-to-back runs up to 3h30.
- Climbing: about 1150 m rising to 3500 m a week (the course averages 34.5 m per km).
- Race-specific: canyon repeats, 20-min climbs, downhill durability, heat and night runs, big back-to-backs, a dress rehearsal.
- Strength: two RunForce 45-min sessions built in the TrainingPeaks Strength Builder (A: Force & Posterior Chain; B: Single-Leg & Mountain Durability), with a demonstration video for every exercise.
Heart Rate Training

Every run is prescribed in RunForce heart-rate zones (% of max HR), with a field check in week 1 and decoupling checks later. Workouts explain how to use HR on climbs, heart-rate lag on short reps, cardiac drift and the effect of heat.
