Virtual Tour de France 2020 – Live Stage 2
In the context of a completely unprecedented health crisis in which most cycling events have been cancelled or postponed, Zwift and Amaury Sport Organisation have decided to do something useful together and create the very first virtual Tour de France. It will be the starting point for a strong solidarity campaign around cycling.
During the first three weekends of July 2020, men’s and women’s professional races will be organised as part of virtual stages of the Tour de France.
