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...

A 200m drift from target altitude across a six-week block is the difference between a productive Hbmass response and a partial one. The dose-response curve for altitude training is approximately linear at moderate altitudes, and the protocol math depends on the system delivering the prescribed altitude reliably across the full duration of...

Erythropoiesis cannot occur without iron. Every haemoglobin molecule contains four iron atoms, and every new red blood cell produced during an altitude block consumes iron from the body's stores. An athlete with depleted iron going into a properly dosed block produces no Hbmass response, regardless of how many hours are accumulated, what...

Rico Rogers, Founder and Director of Box Altitude, raced professionally on the road in Europe for a decade. The French Alps were a working environment. Sierra Nevada was a pre-season fixture. Altitude was not a marketing concept on the World Tour calendar. It was infrastructure, alongside the turbo trainer and the team...

Triathlon is the second-largest sport vertical for serious altitude training after cycling, and the structural reasons are direct. The race spans 4 to 17 hours of sustained sub-threshold aerobic effort. The bike leg dominates the time distribution. Three disciplines stack on top of one another in a training week. The protocol math...
