Speedgoat 50K Training Plan: 20 Weeks, Intermediate, Running Power
Prepare specifically for the Speedgoat 50K with a structured 20-week running power 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 Speedgoat course.
The Race
50 km (31 mi) from Snowbird, Utah, with about 3,450 m (11,300 ft) of climbing between 2,400 and 3,350 m. 13 h cutoff. Repeated big climbs to Hidden Peak on singletrack, ATV tracks and ski roads, Mineral Basin, the tunnel and Cirque Ridge, with steep loose descents.
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 5.5 h rising to 9.7 h of running.
- Long runs: 1h30 to 4h15, with back-to-back runs up to 1h45.
- Climbing: about 1250 m rising to 3300 m a week (the course averages 69 m per km).
- Race-specific: steep hiking repeats, 20-min climbs, heavy downhill durability, altitude guidance, 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.
Running Power Training

Every run is prescribed as % of your Critical Power, with a CP test in week 1 and retests later. Power guides climbs, threshold and interval work precisely; workouts explain when power is less useful (steep descents, very technical ground). Works with Stryd, COROS and Garmin power.
