SoCal Peaks Trail Planning Index

Mountains are useful external tasks—not lifespan calculators.

This updated index preserves TrailGenic’s route inventory while retiring VO₂Max-to-years estimates, historical fueling prescriptions, and the idea that higher is automatically better.

From Longevity Score to Planning Index

The earlier index converted route performance into estimated VO₂Max, METs, and “Longevity Equivalent” years. That conversion is retired. Distance, gain, duration, body weight, altitude, or fasting status cannot produce a defensible personal VO₂Max value or lifespan estimate.

The route inventory remains useful. It is now organized as a planning reference: a way to compare external demands, choose repeatable routes, and build a Personal World Model from actual observations.

How to Read the Table

Distance, gain, and duration are historical TrailGenic session descriptors, not official route specifications, forecasts, records, or prescriptions. Route variations, GPS error, stops, weather, snow, closures, fire, and trail damage can materially change them. Verify current information with authoritative land managers and weather sources.

What the Index Can Support

What It Cannot Support

Engine and Governor

The Engine asks what capacity a route may require and what the person has demonstrated. The Governor asks whether altitude, symptoms, weather, terrain, remoteness, fatigue, pain, illness, equipment, and judgment make the route inappropriate. These are conceptual lenses, not scores.

Personal World Model

Use observation → inference → hypothesis → decision → revision. The table describes external tasks. The individual response must be observed directly, and corrected data supersede prior narratives.

Step 1 — Choose a Reference Tier

Start from routes whose distance, gain, terrain, and consequence fit demonstrated capacity rather than selecting by summit elevation alone.

Step 2 — Verify the Current Route

Check official access, permit requirements, weather, fire, snow, ice, water, trail damage, and seasonal closures immediately before the outing.

Step 3 — Count the Total Dose

Include distance, gain, grade, expected duration, altitude, temperature, load, technical terrain, remoteness, food timing, and descent consequence.

Step 4 — Plan Fuel, Fluid, and Equipment

Use route-specific needs and individual context; historical LMNT counts or fasted completions are not prescriptions.

Step 5 — Set Turnaround and Exit Rules

Decide time limits, symptom rules, weather thresholds, and descent options before starting.

Step 6 — Record Direct Observations

Log the actual route, conditions, duration, gain, exertion, symptoms, food, fluid, and decisions.

Step 7 — Update the Personal World Model

Compare like with like, distinguish observation from inference, and use the result to repeat, regress, substitute, or progress.

Planning Tools

  • Official land-manager access and permit information
  • Current weather, fire, snow, avalanche, and trail-condition sources as applicable
  • Map, navigation, lighting, layers, communication, and emergency plan
  • Individualized food, fluid, and equipment plan
  • Session log for actual conditions, dose, symptoms, and decisions

What is the SoCal Peaks Trail Planning Index?
It is a comparative route catalog organized by terrain and exposure. It is not a longevity score, medical recommendation, or guarantee of current trail conditions.

Why was the Longevity Equivalent removed?
A hike cannot be converted defensibly from route data into VO₂Max and then into personal years of life. TrailGenic has retired that conversion.

Are the durations expected finish times?
No. They are historical TrailGenic session descriptors and can differ substantially by person, conditions, route variation, stops, and device.

Is a higher peak a better healthspan workout?
No. A repeatable lower-consequence route can be more useful than an extreme session. Higher altitude and remoteness add risk, not guaranteed benefit.

Are the historical fasted and electrolyte protocols recommendations?
No. They are removed from the planning table because food and fluid needs are individualized and conditions change.

How should altitude be handled?
Use a separate altitude plan based on ascent profile, sleeping altitude, symptoms, prior response, and reliable descent. Fitness does not prevent altitude illness.

How does the index support the Personal World Model?
It helps select a comparable external task. The actual response then enters the model as observation, followed by explicit inference, hypothesis, decision, and revision.
