What is carbon monoxide rebreathing and why is the entire Tour de France talking about it? Tadej Pogačar and Jonas Vingegaard insist it's "nothing suspicious" and "just a simple test", but others are less convinced

UAE Team Emirates, Visma-Lease a Bike and Israel–Premier Tech all admitted using the controversial test during altitude camps, raising health and
ethical questions — but is it safe and are the concerns justified?

Carbon monoxide has been the talk of the Tour de France this week, the
race's biggest stars and teams fielding questions on a controversial 'rebreathing' technique used to test and optimise riders' altitude
training. However, given the health questions that inevitably follow an admission about inhaling a deadly gas such as carbon monoxide, plus the potential for the practice to be abused for performance gain, it's not hard
to see why so many have raised safety and ethical concerns.

The discussion was sparked by an at-length piece by Escape Collective (link

have access to a carbon monoxide rebreather — an expensive piece of kit
that allows for precise dosing of the gas into the lungs.
