1️⃣ What Is HR Drift (Plain English)

• HR drift = rising heart rate at the same effort
• Signals hydration status, metabolic efficiency, and aerobic base
• Usually invisible in short workouts

2️⃣ Why Gyms Rarely Reveal Drift

• Sessions are too short
• Climate-controlled
• Frequent rest
• External pacing (machines, classes)

Result: fitness without exposure

3️⃣ Mount Baldy as a Drift Test

Using your data:

• 5h+ duration
• Avg HR ~130 bpm
• Declining HR in final hours
• Cold + altitude stress

Interpretation:

The body became more efficient as stress accumulated.

That’s adaptation.

4️⃣ Drift vs Peak HR (Critical Reframe)

• Peak HR = effort
• HR drift = resilience

Two people can hit 155 bpm.
Only one can hold 130 bpm for 5 hours without escalation.

5️⃣ Why This Matters for Longevity

Low HR drift correlates with:

• Mitochondrial density
• Fat oxidation
• Autonomic balance
• Faster recovery
• Lower cardiovascular strain over time

This is capacity, not performance.
