A top Copenhagen official has played down hopes that the Danish capital could soon join the Formula 1 calendar.

Ninna Hedeager Olsen, the deputy mayor for Copenhagen's technical and environment department, told Politiken newspaper that an F1 race in the city is "completely unrealistic".

"The organisation of an event like Formula 1 is so extensive and requires so many resources that it is completely unrealistic for Copenhagen by 2020," she said.

Hedeager Olsen said that another major obstacle is the city disruption the event would cause.

"My administration estimates that Formula 1 could affect central parts of the city for up to nine weeks," she said. "This is of course completely unacceptable."

The 2018 calendar gets underway this weekend in Melbourne.
