A 61 1/2 pound dog travelling along a 700 yard track at about 40 miles-an-hour on Monday broke a 44 year-old record in British Greyhound racing.

The greyhound, Westpark Mustard, won her twentieth race in a row to break the record set in 1930 by the legendary Mick the miller who won 19 straight races.

Westpark Mustard - who is known at her Kennels as Lassie - was bought in Ireland two and a half years ago for GBP 2,500 ($ 5,750).

Since then she has won the twenty races ranging form the 525 yard sprint to the 800 yard distance races. It is a difficult feat because bitches are harder to keep in racing trim than dogs.

She is trained by Tom Johnston along with 60 other greyhounds at his kennels in the countryside of Buckinghmshire.

Westpark Mustard won her 20th race by 6 1/2 lengths after making a bad start and coming through from third position.

And what chance did the bookmakers give of her continuing her record breaking run? Odds of 12-to-one on, with all bets void if she didn't win the race.
