With only a few days to go before the biggest horse racing event in the world – the Grand National, you’ve still got time to get a good price on the horse that you think has the potential to win. Check out the antepost prices on Betfair now. The trouble with the Grand National, though, is that the course is so challenging and always has the potential to throw up a surprise winner that it’s very hard to say with any certainty which horse is the right one to pick.

If you’re one of the 600 million people who will watch the race live on TV, the chances are that you don’t know that much about racing and will just choose a name you like the sound of, one that’s offering a bit of value. In a race that’s open to pretty much any one of the 40 entrants winning, why not just have a go?

But, if you look at the stats of previous Grand National winners, you could choose to have a more educated guess when you place your bets.

One example is the average weight carried by the winner – this is a handicap race after all. During the last thirty years, the average winning weight is 10st-08¾lbs, but many of the favourites this year will carry weights of 11 stones and more.

Another stat to look at is age of the winning horse. Winners in the last three decades have ranged in age, but 80% of them have been aged between 9 and 11 years.

You can also look at horses’ racing records, too. In recent times, 80% of Grand National winners have done hurdle races in the same season they won the Aintree race. And the ten latest National winners had had at least ten races over fences and won races of at least three miles in length.

Looking at each horse with these kinds of stats in mind helps you narrow down your options when it comes to choosing which horse to back.
