Hardrock 100 Training Plan: 26 Weeks, Intermediate, Heart Rate
Prepare specifically for the Hardrock 100 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 Hardrock course.
The Race
164 km (102 mi) loop from Silverton, Colorado, with about 10,200 m (33,400 ft) of climbing, an average elevation near 3,400 m and a high point of 4,282 m on Handies Peak. 48 h cutoff. Thirteen major climbs over high passes on trail, jeep road and cross-country tundra: snowfields, scree, stream crossings, exposed ridges and some scrambling. Afternoon storms and freezing nights.
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. Beginner means first Hardrock, not first ultra: entry requires a qualifying mountain 100 and a lottery place.
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 1600 m rising to 5250 m a week (the course averages 62.2 m per km).
- Race-specific: long steep hiking climbs, altitude guidance, technical descending, night runs, big back-to-back weekends, 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.
