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...
Sleeping at moderate altitude through normobaric hypoxia is among the most studied physiological interventions in endurance sport, with several decades of peer-reviewed research and an established safety profile across multiple athletic populations. For the cautious first-time evaluator, the partner of an athlete who is the other decision-maker in a household purchase, or...

England’s Mexico City World Cup challenge is not just tactical — it is physiological. At 2,240 metres above sea level, altitude can reduce oxygen availability, increase fatigue, slow recovery between sprints, and change how the ball travels. This article looks at how England prepared, what they could not fully adapt to, and...
Injured athletes face two compounding losses. The first is the loss of training stimulus that drives ongoing adaptation. The second is the gradual erosion of the haematological infrastructure that sustained aerobic performance depends on. Together these produce faster fitness decline than most athletes anticipate, and the rehabilitation timeline often runs longer than...
Indoor cycling has become a serious training environment rather than a winter compromise. Zwift, TrainerRoad, Wahoo SYSTM, MyWhoosh, and Rouvy have built an entire culture of structured power-based training that runs alongside outdoor work in most serious programmes. For time-constrained cyclists, masters athletes managing joint loading, and World Tour pros in their...
Direct competitors gloss over this topic because doing so feels commercially safer. Box Altitude takes the opposite position. Side effects are real, manageable, and worth discussing openly. The athlete who runs the protocol with full information makes better decisions than the athlete who is told there is nothing to manage. This article...
