When and what time is the Grand National 2017?
The horses racing at Aintree will go to post at 5.15pm today, Saturday 8th April. With Saracens vs Harlequins at Wembley, another round of Premier League football and the third round of The Masters, it looks a mouth-watering day of sport.
What TV channel is it on?
The Grand National is on ITV for the first time this year after they won the broadcasting rights to show racing. Ed Chamberlin is their presenter, a familiar face and voice for any football fans out there.
What is the Grand National?
Aintree's Grand National is the most popular jumps race on the calendar as 40 runners take on the daunting obstacle of 30 fences over the course of four and a half miles.
Where is it?
As always, Aintree, which has hosted the race since 1839. The racecourse is situated approximately six miles outside of Liverpool.
What's the weather forecast?
Looking very, very nice. Sunshine and a high of 18C.
Liam Treadwell will miss the ride on Tenor Nivernais in Saturday's Randox Health Grand National after suffering a heavy fall at Aintree on Friday.
Treadwell, who won the 2009 Grand National aboard 100-1 shot Mon Mome, only made it as far as the first fence before falling from Bright New Dawn in the Topham Chase.
The field had to bypass the obstacle second time around as Treadwell was being attended to by medics.
Venetia Williams, trainer of both Bright New Dawn and Tenor Nivernais, was initially hopeful Treadwell would be fit for the Aintree spectacular, but later discovered he would not be available.
Leading jockey Aidan Coleman will take over in the saddle aboard the 10-year-old.
Williams said: "Liam was taken to hospital for precautionary checks and has let me know that unfortunately, he is out for Saturday.
"They are keeping in overnight and he says there is no way he's going to be able to ride.
"The plan is for Aidan Coleman to ride Tenor Nivernais."
Which horses are running?
The final field of 40 runners were confirmed on Thursday 6 April.
110 horses entered the race this year, and they were all assigned a weight by the British Horse Racing Authority's head of handicapping.
The handicap system is simpler than it sounds, and is designed to create as close a race as possible. The better horses carry the most weight while the outsiders carry the least. Each horse has an OR (official rating) and this will largely determine the weight they carry. The maximum for this year's National is 11st 10lbs and the minimum is 10st. In theory, the handicap system aims to create a dead heat but this cannot happen in practice.
The weights for this year's race were released on Valentine's Day and the horses listed in descending order from most weight to least.
What are the Grand National betting odds?

What are some of the famous fences?
The Aintree fences are not quite as perilous as they were once upon a time after a series of alterations. However, they are still the most notorious obstacles in the business and enough to make the palms of any jockey sweat.
Becher's Brook: The sixth and 22nd fence in the race may not be the biggest, but it's difficulty comes from the fact the landing side is 10 inches lower than the take off side. Named after Captain Martin Becher, a jockey who fell at this stage and hid in the brook to avoid injury.
Valentine's Brook: Named after a horse that allegedly jumped it backwards in 1840. More likely, the horse spun around in mid-air to create the optical illusion that its hind legs landed first.
The Chair: The tallest fence on the course now stands a five foot three inches.
Foinavon: One of the smaller fences is named after the 100/1 shot who avoided a disastrous pile-up here in 1967 and went on to win.
Canal Turn: As the name suggests, horses must take a sharp turn to the left after jumping this five foot obstacle. Another Aintree myth is that horses used who refused to turn ended up in the Liverpool and Leeds canal.
Are there tickets left?
There are some £27 tickets left in the Steeplechase enclosure via the official Grand National website. All other enclosures and stands are sold out.
