The Highest Marathon In the World

by | Altitude Training Information, Endurance, Hiking, Climbing and Mountaineering

Racing from Everest Base Camp

At 5,364 metres above sea level, the air is thin, the terrain is unforgiving, and every step demands focus.

This is where the Everest Marathon begins.

Known as the highest marathon in the world, the race starts near Everest Base Camp and descends 42 kilometres through the Khumbu Valley to Namche Bazaar. It’s not just a test of endurance—it’s a test of how well you can perform when oxygen is limited, fatigue is constant, and the environment offers no margin for error.

For Altitude members Michael and Paul, this wasn’t just a race. It was the final chapter of a much larger journey.

The Road to the Start Line

Before race day, there is the trek.

Reaching Everest Base Camp requires days of steady climbing through the Khumbu region—moving from Lukla through villages like Namche Bazaar, Tengboche, and Lobuche. The terrain is rugged, the elevation gain is relentless, and the effects of altitude build gradually with each passing day.

By the time runners reach Base Camp, they’ve already been tested.

Michael and Paul approached this phase with purpose, building the physical and mental foundation needed not just to arrive—but to continue.

Higher Still: Kala Patthar

Before lining up for the marathon, they pushed even further.

From Base Camp, Michael and Paul climbed to the summit of Kala Patthar (5,545 m), a nearby peak known for offering one of the best views of Everest and the surrounding Himalayan range.

It’s a demanding ascent at altitude—steep, exposed, and made more difficult by already accumulated fatigue.

But it served a purpose.

At elevations like this, every hour spent moving becomes part of your preparation. It reinforces pacing, breathing, and the ability to stay composed when conditions are at their most challenging.

Race Day: The Everest Marathon

The Everest Marathon is unlike any other race in the world.

It begins at extreme altitude, where oxygen levels are significantly reduced, and descends through technical terrain—rocky trails, uneven footing, and long stretches that demand constant attention.

There is no cruising.

Every kilometre requires effort.

For Michael and Paul, the goal wasn’t just to finish—it was to move consistently, stay controlled, and manage the demands of both the terrain and the altitude.

After 12 hours, 37 minutes, and 20 seconds, they crossed the finish line together in Namche Bazaar—placing 191st and 192nd, respectively.

More Than a Race

For Michael and Paul, the Everest Marathon wasn’t just about the finish time.

It was about the full experience—trekking through the Khumbu, standing at Everest Base Camp, climbing higher, and then taking on one of the most unique endurance challenges in the world.

It’s a reminder that some goals aren’t meant to be approached in isolation.

They’re built step by step—through preparation, through shared experience, and through the willingness to keep moving forward, even when conditions are far from ideal.

How to Train for a High-Altitude Triathlon

by | Altitude Training Information, Endurance, General Fitness

Where Endurance Meets Elevation: How to Perform When Oxygen is Limited

Training for a triathlon is already a test of endurance, discipline, and resilience. Add high altitude to the mix, and you’re looking at an entirely different level of challenge—and opportunity. Whether you’re eyeing a race in the Colorado Rockies, the Alps, or the Andes, preparing properly can mean the difference between surviving and truly performing.

Why Altitude Matters

At high elevations (usually above 1,500–2,000 meters or 5,000–6,500 feet), the air contains less oxygen. That means your muscles—and your brain—receive less of the fuel they rely on for performance. This can lead to:

  • Reduced aerobic capacity (VO₂ max)

  • Faster onset of fatigue

  • Increased breathing and heart rate

  • Higher perceived exertion

  • Slower recovery

In short: what feels hard at sea level feels harder at altitude.

how to train for a high-altitude triathlon

Training Smart: Your Pre-Race Strategy

1. Get Acclimatized If You Can

If your schedule allows, arrive at race altitude 10–14 days before your event. This gives your body time to adjust to the lower oxygen levels, producing more red blood cells and improving oxygen transport.

Can’t spare the time? Research shows that arriving just a few hours before competition (the “fly‑in/fly‑out” strategy) is a plausible last‐resort, but it hasn’t been proven superior to arriving the evening before. In one controlled study, cyclists who arrived just hours before their 20 km time trial did not outperform those who flew in the night before—physiological measures (like sleep quality, ventilatory response, plasma volume) did not differ significantly between approaches.

2. Incorporate Altitude Simulation Into Your Training

If you’re training at sea level, simulated altitude training can help bridge the gap. Training in a hypoxic environment—like Altitude Athletic Training’s 10,000 ft facility in Toronto—can trigger beneficial adaptations that support endurance performance, such as:

  • Improved mitochondrial efficiency (more power output at the same effort)

  • Greater capillary density (better oxygen delivery to muscles)

  • Enhanced lactate buffering capacity (delay fatigue and recover faster)

  • Increased ventilatory response (more efficient breathing under stress)

Structured altitude exposure can improve aerobic efficiency and fatigue resistance, helping you perform better at elevation without needing to live in the mountains.

3. Focus on Aerobic Efficiency

At altitude, you burn through your energy stores faster and accumulate fatigue more quickly. Training your aerobic system to be more efficient is key. Prioritize:

  • Long, steady-state efforts at Zone 2 (around 65–75% of max HR)

  • Brick workouts (bike-to-run) at controlled intensities

  • Strength training to improve muscular economy and injury resilience

4. Dial in Your Race Pace and Nutrition

Pacing at altitude is tricky—what feels sustainable early on can quickly lead to blow-up. Train with heart rate and perceived exertion as your guide, and use tools like lactate threshold or VO₂ testing to set accurate zones.

Also, hydration and fueling needs are higher at altitude. The air is drier, and sweat evaporates faster, increasing the risk of dehydration. Train your gut, know your fueling strategy, and stay on top of hydration.

5. Don’t Neglect Recovery

Sleep quality often takes a hit at altitude. Combine that with the physiological stress of training and racing, and your body needs more time to recover. Use tools like:

  • Compression

  • Breathwork

  • Active recovery sessions

  • Low-intensity hypoxic training to promote adaptations without added strain

Training for a high-altitude triathlon isn’t just about working harder—it’s about working smarter. Prepare your body to adapt, get familiar with how altitude affects your pace and effort, and arrive confident that you’ve done everything possible to be ready.

2. Use Heart Rate Monitoring to Guide Your Effort

Heart rate monitoring can be an invaluable tool in managing your effort throughout the Leadville Trail 100. With the high altitude and long distance, it’s easy to overexert yourself early in the race, which can lead to fatigue and a potential drop in performance later on.

Tip: Incorporate heart rate training into your Leadville 100 training plan to understand your optimal effort levels at different intensities and altitudes. On race day, use your heart rate monitor to stay within your target zones, especially in the early miles. This can help prevent you from going out too fast and ensure you conserve energy for the challenging sections later in the race. Monitoring your heart rate can also alert you to any signs of dehydration, overexertion, or altitude sickness, allowing you to adjust your pace or nutrition strategy accordingly.

 3. Master Your Nutrition and Hydration Strategy

Fueling your body properly during a 100-mile race is critical. The combination of long hours on your feet, high altitude, and unpredictable mountain weather means your body will be under immense stress. Proper nutrition and hydration can make or break your race.

Tip: During your training, experiment with different foods, gels, and hydration products to find out what works best for you. Your nutrition plan should include a balance of carbohydrates, proteins, and fats, with an emphasis on easily digestible foods that you can consume on the go. Hydration is equally important, especially considering the dry mountain air that can increase dehydration risk. Remember to include electrolytes to maintain balance, particularly sodium and potassium, which are vital in preventing cramps and maintaining energy levels. Dialing in your nutrition and hydration strategy ahead of time will help you avoid GI issues and energy bonks during the race.

by | Altitude Training Information, Endurance, General Fitness, Hiking, Climbing and Mountaineering, Hypoxic Training Resources

In recent years, the term “biohacking” has gained significant traction, capturing the imagination of individuals seeking to optimize their physical and mental performance through unconventional means. Among the myriad techniques and methodologies encompassed by this umbrella term, hypoxic training stands out as a particularly intriguing approach. But is hypoxic training truly a form of biohacking, or does it represent a natural adaptation rooted in our evolutionary history? Let’s delve into this fascinating topic.

Hypoxic Chamber

Understanding Hypoxic Training

Hypoxic training involves exposing the body to reduced oxygen levels, typically achieved by simulating high-altitude environments or utilizing specialized equipment such as altitude tents, masks, or chambers. Athletes, fitness enthusiasts, and even medical professionals have long been intrigued by the potential benefits of training in hypoxic conditions.

The Biohacking Perspective

From a biohacking standpoint, hypoxic training fits squarely within the realm of manipulating environmental variables to elicit specific physiological responses. Proponents argue that by subjecting the body to oxygen deprivation, one can trigger adaptations that enhance endurance, cardiovascular function, and overall performance. This perspective aligns with the broader ethos of biohacking, which revolves around leveraging technology, lifestyle modifications, and unconventional practices to optimize human biology.

Evolutionary Roots

However, an alternative viewpoint suggests that hypoxic training is not so much a novel biohacking technique but rather a rediscovery of our body’s innate ability to adapt to changing environmental conditions. Throughout human history, populations living at high altitudes, such as the Andean or Tibetan peoples, have developed unique physiological adaptations to thrive in oxygen-deprived environments. These adaptations include increased red blood cell production, enhanced oxygen utilization, and improved aerobic capacity.

Bridging the Gap

So, where does hypoxic training fit within the biohacking landscape? The answer may lie in its fusion of modern technology with ancient evolutionary mechanisms. While the basic concept of hypoxic training may not be revolutionary in itself, the innovative tools and methodologies employed to simulate altitude conditions represent a quintessential aspect of biohacking. By harnessing our understanding of human physiology and leveraging cutting-edge technology, individuals can fine-tune their training regimens to achieve specific performance goals.

The Science of Adaptation

Regardless of whether one views hypoxic training as a form of biohacking or a natural adaptation, its efficacy is supported by a robust body of scientific research. Studies have shown that exposure to hypoxic conditions can stimulate the production of erythropoietin (EPO), a hormone that regulates red blood cell production, leading to increased oxygen-carrying capacity. Additionally, hypoxic training has been linked to improvements in aerobic endurance, mitochondrial function, and vascular health.

Conclusion: A Blend of Innovation and Tradition

The debate over whether hypoxic training qualifies as a form of biohacking ultimately hinges on one’s perspective. While some may view it as a cutting-edge technique born from the intersection of science and experimentation, others may see it as a rediscovery of ancient physiological adaptations honed over millennia. Regardless of semantics, hypoxic training offers individuals a powerful tool for enhancing physical performance and pushing the boundaries of human potential. Whether you approach it as a biohacker seeking to optimize every facet of your biology or as a student of human evolution embracing our ancestral heritage, the benefits of hypoxic training are undeniable.
