A research-led look at hypoxic training in Thoroughbred horses, including VO₂max, exercise performance, oxygen concentrations used in studies and the limitations of the evidence.
See how Box Altitude delivered a large simulated-altitude training environment and four altitude-enabled apartments at NZCIS in Upper Hutt, New Zealand.
Most athletes measure training in hours per week. But sleeping at simulated altitude can add hundreds of hours of hypoxic exposure without adding another workout. Here is why the invisible training block matters.
A sourced catalogue of professional teams, clubs and high-performance organisations using altitude rooms, hypoxic chambers, altitude houses and simulated-altitude systems.
Josh Kerr, Michael Phelps, Diplo and other famous athletes and public figures have been publicly reported using altitude rooms, chambers or tents. Here are the documented examples and sources.
Prepare for Kilimanjaro altitude with appropriate trekking training, ascent planning and optional simulated-altitude exposure at home.
How to use simulated altitude and an altitude tent as part of Everest preparation before departure, while preserving appropriate on-mountain acclimatisation and safety planning.
How mountaineers can use simulated altitude and altitude tents before Everest, Kilimanjaro, Aconcagua and other high-altitude expeditions, without replacing on-mountain acclimatisation.
Calculate how many F20 altitude generators your room may need using Box Altitude's preliminary planning guides: approximately 16 m³ per F20 for bedrooms and 12 m³ per F20 for training rooms.
Altitude room cost depends on room volume, use and generator capacity. In Australia, the Box Altitude Bedroom System starts from AU$10,900 for a suitable one-F20 sleeping space.
IHHT has gained attention as a convenient way to experience short bouts of hypoxia, but how does it compare with spending 8–10 hours sleeping at simulated altitude? We compare IHHT with altitude sleep, looking at exposure time, physiological adaptation, VO₂ max, endurance performance and what the research actually supports.
Heat training can improve VO₂ max and even haemoglobin mass, but sleeping at simulated altitude has a major practical advantage for endurance athletes: prolonged hypoxic exposure can be accumulated overnight without adding another training or recovery session. Compare the latest heat research with Live High, Train Low, altitude sleep and haemoglobin-mass adaptation.
Compare the Box Altitude Sleep Cloud King and Hypoxico Everest Summit II, including price, tent size, noise, altitude range, oxygen monitoring and app control.
Oxygen Coach was born from years of working with professional athletes, Olympic champions, world champions and world-record holders. Discover why we built a platform designed to bring altitude exposure, physiological data, training and recovery together — and make the science of oxygen adaptation easier to understand.
A practical 30-night altitude sleep framework for swimmers and coaches. Explore the research, progressive altitude exposure, iron and recovery monitoring, benchmark swim sets and how Oxygen Coach can help track an athlete’s response.
Planning altitude training before a marathon? Learn when to start, how long to sleep at altitude, how to progress your exposure, when to stop before race day, and how Oxygen Coach can help track your individual response.
Discover Oxygen Coach, the app created by Box Altitude founder Rico Rogers to help athletes track altitude exposure and understand their response over time.
Altitude training was once treated as a short block before a major race. Today, a more useful model is emerging: build the adaptation, then use a smaller, individualised hypoxic dose to help preserve it through the season—including the off-season.
How much could altitude sleep exposure improve your running, cycling, swimming or triathlon performance? Explore the science behind altitude adaptation and use the Box Altitude Performance Calculator to estimate your potential performance gain and projected race time.
Trail and ultra running is the endurance sport where altitude training delivers the most from a single structural intervention. The reason is direct. The protocol produces two distinct adaptations, and trail runners benefit from both. The first adaptation is haematological. Increased Hbmass and the sustained aerobic performance gain that comes with it....
Compare an altitude bedroom with a Sleep Cloud tent across installation, cost, comfort, portability and shared use. Choose the format that fits your room and routine, without assuming identical results for every athlete.
Josh Kerr’s altitude strategy extended far beyond a traditional training camp. Living and training at moderate altitude in Albuquerque, he then slept at a higher simulated altitude in a Box Altitude bedroom—creating an around-the-clock approach to altitude exposure. Discover how this “live medium, sleep high” model became part of the preparation behind...
The masters demographic is structurally important to endurance sport. Race fields at Western States, UTMB, Boston, Kona, and the broader competitive endurance calendar carry meaningful representation in the 45 to 65 age bracket. The serious masters athlete is typically experienced, self-aware, and pursuing performance inside a different physiological context than the athlete...
Project 222: Inside Josh Kerr’s World Record Journey—and Box Altitude’s Role Some world records happen unexpectedly. Others are planned years in advance. Josh Kerr’s historic 3:42.66 mile world record was the latter. Long before stepping onto the track at London’s Diamond League meeting on 18 July 2026, Kerr publicly announced his ambition...
