In accordance with the Tour de France health protocol, developed in the framework of the Union Cycliste Internationale’s (UCI) rules for the return of the road cycling season in the context of the coronavirus pandemic, the entire “race bubble” was tested on the 7th and 8th September. With all those with accreditations being tested within the 5 days preceding the Grand Départ in Nice and the “race bubble” once again being tested upon arriving on the Tour, this is the 3rd testing campaign since the beginning of the Tour. A 4th test campaign is scheduled, with the same conditions, for the next rest day, in Isère on the 14th September. Its objective is to guarantee the health of the race for the riders and accredited personnel. A total of 841 tests were performed.
