With just days to go before the Grand National gets underway at Aintree Racecourse, it's fair to say the race has seen its fair share of incredible incidents in its near 200 year history.
The first Grand National was run in 1839 - It's the most valuable jump race in Europe with a prize fund of around £1m. The handicap steeplechase has an official distance of about four miles and contains 30 fences over two laps.
With an estimated 500 to 600 million people expected to watch the Grand National from over 140 countries, the race tempts millions of people who don't usually bet on horse racing into having a flutter. There will also be in the region of around 150,000 racegoers at Aintree to watch the big race alone.
