The five-day Volta ao Algarve UCI ProSeries cycling race has been postponed due to a surge in Covid-19 infections in Portugal.
The event was scheduled to start on February 17 but has been moved provisionally to May 5-9.
"Postponement is a difficult decision, but it has become inevitable, given the evolution of the pandemic situation in Portugal," a statement said.
