Workout Description

12.2 km trail/vertical run for time. 6.1 km uphill with 1220 m of gained elevation, descent on the same path. Net average slope 19.5% Slope breakdown: 0–1.2 km: flat 1.2–1.7: slope +12% 1.7–3.2: slope +40 to +46% 3.2–5.7: slope +11 to +31% 5.7–6.1: slope +3%

Why This Workout Is Very Hard

This is a 12.2 km mountain run with 1220m elevation gain—a continuous, unbroken endurance effort lasting 60-90+ minutes for average athletes. The brutal slope profile (40-46% grades mid-route) creates severe leg fatigue and metabolic demand. No rest periods, no breaks, pure aerobic/anaerobic suffering. The descent compounds quad damage. This exceeds typical CrossFit conditioning and demands serious trail running fitness.

Training Focus

This workout develops the following fitness attributes:

  • Endurance (9/10): Sustained 12.2 km trail run with 1220 m elevation gain demands exceptional cardiovascular capacity and aerobic output over extended duration.
  • Stamina (8/10): Continuous uphill and downhill running for 45-90+ minutes exhausts leg muscular endurance and sustained force production against gravity.
  • Strength (4/10): Steep slopes (up to 46%) require significant leg strength to drive uphill; descent demands eccentric strength control but not maximal effort.
  • Flexibility (3/10): Trail running requires basic ankle mobility and hip range of motion; uneven terrain demands proprioceptive awareness but not extreme flexibility.
  • Speed (3/10): Steady pacing strategy dominates; terrain and elevation prevent high-speed cycling. Downhill allows faster movement but controlled descent prioritized.
  • Power (2/10): Primarily a grind workout; minimal explosive demands. Steep sections require sustained power output rather than explosive bursts.

Benchmark Notes

The primary limiter is sustained aerobic capacity and leg strength on the 40-46% grade sections (1.7–3.2 km), which force most athletes into a slow grind or hands-on-knees scramble. L5 (~95 min) reflects a reasonably fit CrossFitter who can power-hike the steep sections and run the moderate grades, with a faster descent offsetting the brutal climb.

Modality Profile

Run is a cyclical cardio movement classified as Monostructural (M). Single movement workout = 100% of that modality.
