Record crowd expected at Aintree05:30, Apr 5 2008
A record crowd is expected for the 161st John Smith's Grand National at Aintree racecourse in Liverpool.
Forty riders will race in the world's most famous steeplechase with Cloudy Lane - trained by Red Rum trainer Ginger McCain's son Donald - the favourite.
Along with Slim Pickings and Comply Or Die, Cloudy Lane - ridden by 27-year-old Jason Maguire - is expected to lead the field.
He is being described as the clearest favourite to win since Red Rum in the 1970s.
Ladbrokes spokesman David Williams said: "The name McCain sends shivers down our spine at Grand National time.
"Cloudy Lane is fast becoming the most popular public horse since Red Rum. We fully expect the whole nation to wake up on Saturday morning and back him.
"Quite simply, if Cloudy Lane wins we're doomed. The figures don't bear thinking about."
Bookies are predicting betting on the four-and-a-half mile race will be a record, with a figure somewhere near the £300 million mark.
