The Tour de France has reinstated COVID-19 protective measures, requiring race organizers, media, and guests to wear masks when in contact with riders and team staff. This protocol was announced by race organizer ASO on Sunday morning after several recent COVID-19 cases among the peloton.

“In order to limit health risks, it is now compulsory to wear a mask in the various areas where you will be in contact with the riders and members of the cycling teams,” read the statement from the ASO.

Riders who have abandoned the race due to the virus include Tom Pidcock (INEOS Grenadiers), Juan Ayuso (UAE Team Emirates), and Michael Mørkøv (Astana-Qazaqstan). Geraint Thomas (INEOS Grenadiers) remains in the Tour despite testing positive, as the rules currently allow.

“There are so many people at the start and finish. COVID doesn’t just enter the peloton; it comes from outside,” said Remco Evenepoel of Soudal-QuickStep. Evenepoel has recently been wearing a mask in the mixed zone before and after stages and has called for the organization to enforce stricter COVID-19 measures.
