Tahoe Rim Trail 50K Training Plan: 20 Weeks, Intermediate, Heart Rate
Prepare specifically for the Tahoe Rim Trail 50K with a structured 20-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 Tahoe Rim Trail course.
The Race
48 km (30 mi) on the Tahoe Rim Trail, Nevada, with about 1,800 m (6,000 ft) of climbing, up to 2,808 m near Snow Valley Peak. Singletrack past Marlette Peak and Snow Valley Peak, the Capital to Tahoe Trail and a sun-exposed descent.
Who It Is For
You run 4-5 times a week (about 5-6 h), have finished a trail 30K-50K, and run 90 min long runs.
Your 20 Weeks
- Phases: Preparation week 1, Base weeks 2-7, Build weeks 8-13, Specific weeks 14-18, Taper week 19, race week 20.
- Weekly: 5 runs and 2 strength sessions, about 5.3 h rising to 9.7 h of running.
- Long runs: 1h30 to 4h15, with back-to-back runs up to 1h45.
- Climbing: about 850 m rising to 2350 m a week (the course averages 37.9 m per km).
- Race-specific: mountain repeats, climb tempo, downhill running, altitude guidance, 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.
