Broken Arrow Skyrace 23K Training Plan: 20 Weeks, Intermediate, Heart Rate
Prepare specifically for the Broken Arrow Skyrace 23K 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 Broken Arrow course.
The Race
23 km (14 mi), one loop at Palisades Tahoe, California, with about 1,400 m (4,500 ft) of climbing up to 2,745 m. 7 h cutoff. Emigrant Pass, KT-22, Red Dog Ridge and the ladder on an exposed ridge: rocky, mostly above treeline.
Who It Is For
You run 4-5 times a week (about 4-5 h), have raced a trail half marathon or 20-30K, and run an easy 75 min long run.
Your 20 Weeks
- Phases: Preparation week 1, Base weeks 2-6, Build weeks 7-13, Specific weeks 14-18, Taper week 19, race week 20.
- Weekly: 5 runs and 2 strength sessions, about 4.5 h rising to 7.1 h of running.
- Long runs: 1h15 to 2h30.
- Climbing: about 850 m rising to 2100 m a week (the course averages 59.9 m per km).
- Race-specific: steep hiking repeats, uphill VO2, technical descending, altitude guidance, 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.
