Vermont 100K Training Plan: 26 Weeks, Intermediate, Heart Rate
Prepare specifically for the Vermont 100K 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 Vermont 100 course.
The Race
100 km (62 mi) from West Windsor, Vermont, with about 2,750 m (9,000 ft) of climbing. 25 h cutoff, 9 am start. About 66 km of rolling dirt roads, 32 km of horse trails and a little pavement, shared with the 100-mile runners and the endurance horse ride: constant ups and downs, a hot afternoon and a night finish.
Who It Is For
You have finished at least one 50-mile or 60-80K race, run 5 times a week (about 6-7 h) and do regular 2 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 5.5 h rising to 12.5 h of running.
- Long runs: 1h45 to 6h00, with back-to-back runs up to 3h00.
- Climbing: about 750 m rising to 2550 m a week (the course averages 27.4 m per km).
- Race-specific: runnable tempo and cruise intervals, rolling hill repeats, downhill durability, heat training, 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.
