The world's richest horse race the Dubai World Cup has been called off due to torrential rains in the United Arab Emirates.
The race worth $4 million boasted a field of 13 runners, invited from all around the world.
In two and a half hours a total of 36 millimetres of rain fell, nearly half the yearly total for Dubai.
The race is expected to be run within the week.
The unexpected rain turned the world's richest race into chaos. Out of the 13 intivitees, five were from the UK, three from the USA, one runner each from France, Japan and Australia and two were representing the United Arab Emirates.
Favourite for the race was American runner Siphon trained by Richard Mandella, stable mate Sandpit was second in the betting.
Now it has to be decided when the race will be run and what arrangements will be made for the foreign contenders to stay on in Dubai.
As soon as the heavens opened the fixture was immediately in doubt. Initially the first five races were postponed with the Dubai World Cup due to start the meeting off with the remaining races to follow.
Within two and a half hours,36 millimetres of rain, half the yearly total of Dubai's rain fall landed on the sand track.
Sheikh Mohammed, the race's creator walked onto the track. He poked his stick into the surface and then made a cut throat movement with his hand to signal the meeting was off.
Sheikh Mohammed has already spent 10 million US dollars assembling the world's best horses and some of the best jockeys for an event billed as racing's world championships.
A crowd of 30,000 was expected with the worldwide TV audience estimated at 100 million.
The inaugural race was won last year by American super horse Cigar.
