You have planned your training, set your sleeping altitude and started putting in the hours. Now comes the question: how is your body responding?

At Box Altitude, we hear this from runners, cyclists, triathletes and coaches. Athletes want to understand the exposure they are accumulating, make sense of their wearable data and see how altitude fits into their preparation.

That is why our founder, Rico Rogers, created Oxygen Coach. The app brings altitude exposure, training and recovery data together, helping you follow your own response over time.

Built from the questions our athletes ask

Working with altitude systems means having conversations that go well beyond equipment. How many hours have I accumulated? What happens when I miss a night? Why does my recovery data look different during an altitude block?

Rico was asking many of the same questions himself.

“I’ve been using altitude myself for years, and I still wanted a clearer way to see what I was doing, how much exposure I was actually getting and how my body was responding.”

Oxygen Coach grew from that need: a practical way to bring the information together and make it easier to use.

See your altitude block in hours, not just days

Two athletes can both be on day 12 of an altitude block and have accumulated very different amounts of exposure.

Eight hours a night over 12 nights adds up to 96 hours. Five hours a night over the same period adds up to 60. Record the elevation as well, and the picture becomes more useful still.

Oxygen Coach logs the altitude, duration and type of exposure, whether you are at natural altitude or using a simulated-altitude system. You can follow your accumulated hypoxic dose, compare it with published protocols and explore how your exposure could build towards race day.

For someone using a Box Altitude bedroom or Sleep Cloud, this helps connect the routine of sleeping at altitude with a longer-term training plan.

Understand what the adaptation estimate means

Research gives us a useful starting point for interpreting accumulated exposure. A meta-analysis by Gore and colleagues estimated an average haemoglobin mass increase of approximately 1.1% per 100 hours in the altitude protocols analysed. The main analysis used exposures at elevations of at least 2,100 metres. Read the study.

Oxygen Coach uses published dose-response research to model potential haemoglobin adaptation over time. That gives you an estimate to follow alongside your recorded exposure.

It remains an estimate, rather than a direct measurement of your haemoglobin mass. Individual responses vary, and a percentage increase in haemoglobin mass does not translate directly into the same improvement in race performance.

Make more sense of your wearable data

A recovery number is more useful when you understand the circumstances behind it.

During an altitude block, you may notice changes in overnight oxygen saturation, resting heart rate or HRV. Looking at those numbers alongside the altitude and hours you recorded helps you ask more specific questions. Did the change follow an increase in exposure? Does it happen at the same point in each block? How does it compare with your sleep and training that week?

With compatible wearable data, Oxygen Coach helps you review those patterns in one place.

The purpose is to give you more context for decisions. A poor night or a falling recovery trend still deserves attention; logging altitude does not automatically explain every change.

Plan beyond the next session

Altitude preparation often has a date attached: a marathon, a triathlon, a cycling event or a training camp.

Being able to look ahead makes the exposure log more useful. You can explore how your planned hours accumulate towards a goal, then review what you actually completed and how your body responded.

Oxygen Coach also lets you record heat training, sauna and recovery modalities alongside your broader training data. For athletes combining several approaches, that creates a clearer record of the whole training week.

Start with a clearer picture

Oxygen Coach was built around three questions Rico wanted to answer:

“What have I actually done? How has my body responded? And what should I do next?”

Whether you are using altitude at home or preparing for your next camp, those are useful questions to bring to your training.
