Our Grand National winner prediction algorithm uses primarily factual information such as the number of times a horse has fallen, number of wins over three miles and previous experience of the course or tough jumping courses. However there is also a judgmental element that is blended in.
Together these create an overall ratings for each horse for current form, jumping ability, stamina, course experience, ground preference and also a minor adjustment for stable form.
However there is one thing left for you to do to ensure we get our prediction as accurate as possible.
Select the expected ground/going conditions for the race as our results will vary depending on the ground. The going for the 2014 grand national is likely to be good or good to soft, but we wont know for sure until the day.
