High altitude hunting is different. At 8,000-12,000 feet, oxygen availability drops significantly. Your heart works harder to deliver oxygen to muscles. What feels moderate at sea level becomes challenging at elevation.
The good news: you can train to handle it.
How Altitude Affects Performance
At sea level, oxygen saturation in your blood is typically 98%. At 10,000 feet, it drops to 90%. At 12,000 feet, it can fall to 85%.
This reduced oxygen:
- Increases heart rate for the same effort
- Causes faster fatigue
- Impairs decision-making ability (slight altitude sickness)
- Requires more energy for the same work
Your body adapts—over time. But you need training stimulus to trigger that adaptation.
Breathing and Cardio Training
The most important adaptation is increased aerobic capacity. Your body becomes more efficient at using available oxygen.
Build your aerobic base with:
- Easy jogs: 30-45 minutes, conversational pace (3x weekly)
- Hill repeats: 5-8 x 3-minute climbs with 2-minute recovery between
- Long hikes: 45-90 minutes with elevation gain, practicing the hiking pace you’ll use while hunting
Hill training is especially important. It simulates the constant climbing of mountain hunts.
Altitude Simulation Training
If you have access to actual elevation, spend 2-3 weeks at altitude 4-8 weeks before your hunt. Your body adapts to thinner air.
Can’t train at altitude? Use these methods:
Hypoxic Training: Run on a treadmill at steep incline (simulate elevation’s oxygen demand). This creates some training stimulus, though not identical to true altitude.
Threshold Running: 20-30 minute sustained efforts at 80-85% max heart rate. These force your body to become more efficient at extracting oxygen.
Acclimatization Schedule
When you arrive for your hunt:
Day 1-2: Rest. Drink water (dehydration worsens altitude symptoms). Light activity only.
Day 3-4: Easy activity. 30-minute walks. Let your body acclimate.
Day 5+: Harder activity as you feel capable. Your body needs 5-7 days to fully acclimatize.
Mental Factors
Altitude affects cognition. You might feel slightly confused, foggy, or emotional. This is normal.
Stay calm. Expect the mental change. Accept that decisions might take longer. Plan accordingly.
Practical Pre-Hunt Preparation
8 weeks before your high-altitude hunt:
Weeks 1-4: Build aerobic base with easy running and long hikes.
Weeks 5-6: Add hill work and threshold training.
Weeks 7-8: Maintain fitness but include more hiking at your training elevation.
Include loaded hiking (wearing your hunt backpack) at least 3x weekly for 4 weeks before the hunt.
Supplementation
Iron supports oxygen-carrying capacity. If you’re anemic (fatigue despite training), get blood work done. Iron supplementation can help.
Otherwise, focus on whole foods supporting cardiovascular health: beets (nitrates), leafy greens (iron), berries (antioxidants).
Real-World Application
You’ll arrive at elevation feeling slightly off. That’s normal. Within a week, your body adapts. By week two, you feel stronger.
With proper training and acclimatization, you’ll perform well at altitude. The hunters who struggle are those who didn’t train specifically for elevation demands.
Your preparation now—the breathing workouts, the hill training, the long hikes—directly translates to performance when the altitude tests you.
