Silverstone circuit organisers have apologised to MotoGP fans after the British round of the championship was cancelled due to heavy rain making it too dangerous to race.
"I am so sorry," said managing director Stuart Pringle in a video statement on Sunday, promising to contact all ticket holders during the week.
"In the end the riders felt that the conditions were not going to be right today to race at all and they made the decision not to race."
Organisers had repeatedly postponed the start, having brought it forward to allow plenty of room for manoeuvre, before accepting there was no possibility of beating the bad weather.
They had ruled out already any option of holding the race on Monday.
