‘I never knew it could be misused’ – Jonas Vingegaard weighs in on controversial use of carbon monoxide in cycling

Jonas Vingegaard has addressed the UCI’s latest call for WADA to “take a position” on the use of carbon monoxide (CO) inhalation and stated he would follow whatever guidance is given after it was revealed that teams used the gas as part of altitude training optimisation. 

During the Tour de France, it came to light that the Dane’s Visma-Lease a Bike team, Tadej Pogačar’s UAE Team Emirates and Israel-Premier Tech had used carbon monoxide rebreathers to test blood values at the start and end of altitude camps, Escape Collective reported in July.
