The 2019 Randox Health Grand National takes place on Saturday - and Great British Racing have created a bluffer's guide video that tells you everything you need to know about the big race, plus the ever-useful Sweepstake Kit of the 40 declared runners.
It's the race that everyone loves - even if they take little notice of the world of horse racing the rest of the year.
Last year's winner and hot favourite Tiger Roll has been confirmed in the 40 final declarations - one of 13 runners for trainer Gordon Elliott.
The Grand National is off at 5.15pm on Saturday and will be shown live on ITV.
Good luck if you're having a go!
