Jonas Vingegaard (Visma-Lease a bike) calls for a ban on the use of carbon monoxide

The double winner of the Tour de France (2022 and 2023), second in the last edition behind Tadej Pogacar, recognizes that his team, Visma-Lease a bike, uses it and specifies under what conditions: “My team uses carbon monoxide to measure blood volume and total hemoglobin mass. We inhale the monoxide for the first time, before carrying out a course at altitude. At the end of this, we repeat the operation to calculate our maximum oxygen absorption capacity. »
