Acclimatise with Combine Air

High Altitude Preparation Program

TRAVEL TO altitude with confidence

Travelling to high altitude is an incredible experience, but without preparation, it can also be physically demanding and unpredictable.

Acclimatise with Combine Air is a program designed to help you feel confident, capable, and ready before you go. Delivered inside a simulated altitude environment 3500m above sea-level, it helps your body adapt to lower oxygen levels so you can enjoy the experience, not just endure it.

WHO is THIS program FOR?

This program is designed for people travelling to high-altitude destinations, including:

  • First-time trekkers preparing for their first experience at altitude
  • Experienced adventurers looking to improve energy, recovery, and overall experience
  • Travellers heading to destinations such as Everest Base Camp, Kilimanjaro, Machu Picchu, and similar treks
  • Anyone wanting to reduce the risk of altitude-related issues and feel more prepared before departure

WHY ACCLIMATISATION MATTERS

At altitude, oxygen availability is reduced. This places additional stress on your cardiovascular system, muscles, and recovery capacity.

Without adaptation, this can lead to:

  • Rapid fatigue
  • Reduced performance and energy
  • Difficulty recovering between days
  • Increased likelihood of altitude-related symptoms

Altitude affects everyone differently. Fitness alone does not guarantee readiness.

HOW ACCLIMATISIng WORKS

Acclimatisation is your body’s adaptive response to repeated exposure to lower oxygen levels.

Research on intermittent normobaric hypoxia (repeated exposure to lower oxygen levels at normal air pressure) shows that moderate, controlled hypoxic exposure can meaningfully improve how the body responds to real altitude. In structured protocols, participants demonstrated higher arterial oxygen saturation during subsequent ascent, lower rates of acute mountain sickness, and reduced inflammation and metabolic disruption compared to controls (Gangwar et al., 2019).

During sessions, we use pulse oximetry (SpO₂ monitoring) to track your oxygen saturation in real time inside the simulated altitude environment. This allows us to observe how your body responds to hypoxic stress and adjust exposure progressively and safely. Rather than guessing adaptation, we can see it, guiding your training based on measurable physiological feedback. The result is a preparation strategy that is deliberate, measurable, and grounded in evidence.

THE PROGRAM:

Step 1

Altitude Baseline Assessment

Every participant begins with a comprehensive assessment to understand:

  • Your current fitness and capacity
  • Your travel destination and altitude exposure
  • Your timeline

This assessment forms the foundation of your plan.

Step 2

Personalised Preparation Pathway

Following your assessment, you’ll be guided into a pathway suited to your trip.

All pathways are designed around a minimum six-week lead-in, with program length scaled to trek difficulty and altitude.

Step 3

Prepare with Confidence

As you progress through the program, the goal is simple:

  • Adapt gradually to low oxygen
  • Build confidence and improve tolerance
  • Arrive ready, not uncertain

This assessment forms the foundation of your preparation.
