Box Altitude · Training Cloud
Train indoors. Adapt as if you trained at altitude.
A four-post tent that drops the oxygen content around your treadmill, rower, or smart bike to a thinner-air equivalent — dial in the altitude on your phone, then ride or run as you normally would.
The Training Cloud builds a controlled hypoxic environment around your indoor setup. The Box Altitude App holds your selected altitude steady throughout the session while the F10 or F20 generator feeds the tent. Athletes use it to fit altitude work into a sea-level training week without traveling, and to keep tempo-and-threshold sessions productive without the intensity drop that comes with living at altitude full-time.
Three components, one closed-loop altitude system
The tent holds the environment. The generator changes it. The sensor and app keep the set point honest.
Training Cloud Tent
A four-post tent measuring 2.6 m long, 1.3 m wide, and 2.3 m high — sized to fit a treadmill, rowing erg, or smart-trainer cycling setup with room to move. The shell contains the hypoxic environment so the generator only has to condition the air inside the tent, not your whole training room.
F10 or F20 Altitude Generator
Pulls down the oxygen content of the tent air to your chosen altitude. The F10 is the quieter, multi-purpose unit. The F20 is the more powerful generator and reaches the same set point faster, which matters when you only have a one-hour window before a session.
Altitude Sensor + Box Altitude App
The sensor pairs to the app via QR code and continuously reads the oxygen content inside the tent. The app — iOS, with Android in development — sets the target altitude, monitors time spent at altitude, heat and humidity inside the tent, and tracks your sessions over time.
Why athletes train inside a Cloud
Drop the Cloud over your existing treadmill, Concept2, or Wahoo / Zwift setup. You don't change your training equipment; you change the air around it.
Working at altitude raises the metabolic cost of the same wattage or pace versus a sea-level session — a useful lever for athletes managing body composition alongside performance work.
Set your target altitude, watch the system hold it, monitor heat and humidity, and log the session. No dials on the machine, no guesswork on whether the air is where you set it.
Available in 110-120 V or 220-240 V — same system, ordered for the grid you have. Free standard shipping, with deliveries typically inside 30 days.
How a Training Cloud session works
Set the altitude, then train as you would at sea level
Open the Box Altitude App, dial in the altitude you want — most athletes work between 2,000 and 3,000 m for indoor sessions — and let the generator condition the tent air. Step in, start your treadmill or erg, and run the workout you'd already planned. The app holds the set point for as long as the session lasts.
Built around your existing indoor rig
The 2.6 m × 1.3 m footprint covers a treadmill, a single Concept2 rower in its rowing position, or a smart-trainer bike with room for a fan. The 2.3 m height clears most home-gym ceilings and gives a running stride enough headroom to feel normal.
F10 versus F20 — which generator does what
Both generators reach the same maximum altitude. The difference is how fast they get there and how hard they have to work to hold it. The F10 is the standard unit — quieter, multi-purpose, well-suited to athletes who pre-condition the tent before a session. The F20 is the heavier unit for athletes who want the tent at altitude in minutes, not tens of minutes, or who plan to use the system for long blocks of continuous work.
Choose your generator
Same tent, sensor, and app. Pick the generator that matches how fast you want the tent at altitude.
F10 Altitude Generator
The quieter, multi-purpose generator. Pre-conditions the tent ahead of a session and holds the set point through the workout. The default pick for most home setups.
- Reaches set points up to 4,000 m
- Efficient, quiet operation
- Available in 110-120 V or 220-240 V
F20 Altitude Generator
The more powerful generator. Reaches the same altitudes as the F10, faster — useful when you want minimal lead time before a session or plan to run long, continuous blocks at altitude.
- Reaches set points up to 4,000 m
- Faster time-to-altitude than the F10
- Available in 110-120 V or 220-240 V

Frequently asked questions
Both reach the same maximum altitude of 4,000 m. The F20 is the more powerful unit and reaches the set point faster, which matters when you want minimal lead time before a session or plan to run long continuous blocks at altitude. The F10 is the standard, quieter, multi-purpose generator most home athletes choose.
The tent measures 2.6 m long × 1.3 m wide × 2.3 m high — sized for a treadmill, a rowing erg, or a smart-trainer cycling setup such as Zwift or Wahoo.
Box Altitude lists 2,500 m (8,202 ft) as the most beneficial training set point, balancing performance adaptation against the ability to add subsequent training load. The system itself can reach 4,000 m if you want to push higher.
From your phone. The Box Altitude App talks to the Altitude Sensor inside the tent (paired via QR code) and to the F10 or F20 generator. You set the target altitude in the app and the system maintains it. The app also tracks heat, humidity, and time spent at altitude across sessions.
Yes. The system is offered in 110-120 V and 220-240 V versions — choose the voltage that matches your country and grid when you order.
Living and training at altitude full-time tends to compromise workout intensity because lower oxygen limits how hard you can push. Box Altitude's approach is to add altitude exposure to a sea-level program — train hard in normal air, then layer altitude work into specific sessions. This keeps intensity high while still capturing the adaptive benefits of altitude.
