Broken Arrow Skyrace 23K Training Plan: 20 Weeks, Beginner, Heart Rate
Prepare specifically for the Broken Arrow Skyrace 23K with a structured 20-week heart rate training plan for runners new to this distance. It builds the aerobic durability, basic climbing and descending strength and race-day routines you need to finish the Broken Arrow course strong and healthy.
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 3 times a week (about 2.5-3 h), can run 60 min continuously and have finished a 10K or short trail race.
Your 20 Weeks
- Phases: Preparation weeks 1-2, Base weeks 3-7, Build weeks 8-13, Specific weeks 14-18, Taper week 19, race week 20.
- Weekly: 4 runs and 2 strength sessions, about 2.8 h rising to 5 h of running.
- Long runs: 1h00 to 2h15.
- Climbing: about 400 m rising to 1100 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. Workouts explain how to use HR on climbs, heart-rate lag on short reps, cardiac drift and the effect of heat.
