The Union Cycliste Internationale (UCI) announces that the 2021 Tissot UCI Track Cycling World Championships, which were to take place from 13 to 17 October in Ashgabat (Turkmenistan), have been cancelled in their initial format, at the request of their organisers, as the health constraints and restrictions linked to the Covid-19 pandemic make it impossible to stage the event in the country. The UCI is currently in contact with several potential alternative organisers with a view to moving the event to another venue on the same dates. The name of the new host city will be communicated as soon as possible.
