TrailGenic Science

When hiking a moderate route like Baldy Bowl Trailhead → Ski Hut/Lodge (~6.2 miles round trip, 1,605 ft gain, ~7,800 ft high point), fueling choice can completely change the physiological result.

Autophagy Mode (Fasted + Electrolytes)

- Lowers glycogen demand, prompting earlier fat oxidation  

- Promotes cellular cleanup (autophagy), mitochondrial renewal, and long-term endurance adaptations  

- Works best for moderate-intensity efforts where glycogen depletion isn’t the limiter  

- Typical setup: water + electrolytes (e.g., LMNT), steady Zone 2–low Zone 3 pace

Normal-Fueled Mode (Pre-hike Carbs or Snacks)

- Extends glycolytic dominance, delaying the onset of autophagy  

- Provides more short-term power output but reduces time in deep cellular repair mode  

- More beneficial for consecutive heavy training days when rapid recovery is the priority  

- Typical setup: small carb preload or mid-hike snack; trade-off is less autophagy time

Why It Matters

The same trail, distance, and elevation can yield completely different benefits depending on fueling strategy:  

- Fasted autophagy hikes: build a deeper aerobic base, metabolic flexibility, and cellular health  

- Fueled hikes: focus on power output and rapid recovery readiness  

For moderate gain / submaximal effort routes, fasted training often delivers the best return for long-term endurance and cellular resilience.
