Yesterday was Mascot Grand National day at my local horse racing track, Huntingdon. There is nothing like the site of 50+ 6ft tall mascots stampeding down a racecourse jumping over tiny little hurdles. This year it was won by Wacky Macky Bear from Saffron Waldron FC, although the course commentator kept calling him Wacky Backy much to everyone's amusement.
The race now in it's 9th running is so famous it was shown live on Sky News. Hopefully you'll find the coverage at Sky News (link removed as Sky removed article)
The best thing is that you can bet on the race itself.
After the mascot race, they have a full set of races for the rest of the afternoon. I managed to win enough on the first race to cover my bets for the rest of the afternoon, which was a surprise as my horse came in second, however the bookie made a mistake and paid out for a win, shame.
