Mervin Gray, part of the Top Man Racing Syndicate who own Jazzy Matty, speaking to BBC Radio 5 Sports Extra: "We just can't believe it, we knew we had a great chance. He loves this hill, he has proved it before. What a day, a very special moment.
"There's somebody looking over us today, it can only be one man.
"Danny [Gilligan] did well, gave him plenty of space. We are overwhelmed."

Marine Nationale and Jazzy Matty were the two horses Michael O'Sullivan rode to victory on the opening day of Cheltenham two years ago. They have won races back to back today.
It is surreal, I have hairs standing up on the back of my neck.

Mervin Gray, part of the Top Man Racing Syndicate who own Jazzy Matty speaking to ITV Racing: "That was some performance from Jazzy Matty. We knew he had more in the tank. Should we mention Michael O'Sullivan as well? What a legend. We're all overcome.
"Somebody is watching over us today and it's only one man, credit to him."

Jazzy Matty jockey Danny Gilligan speaking to ITV Racing: "I think we all know there is someone very special looking down on this, especially with Marine Nationale earlier and now this. Someone very special is looking down at us today.
"He never missed a beat, it's all down to the lads who do the work every day. I'm just thrilled to get the result."

It was written in the stars.
Jazzy Matty was the other horse Michael O'Sullivan rode to victory at Cheltenham two years ago.
Irish jockey O'Sullivan, who died in a fall last month, won the Fred Winter Hurdle for trainer Gordon Elliott in 2023.

It really is just absolutely extraordinary that these Marine Nationale and Jazzy Matty won today.

Incredible stuff. The two horses you would associate Michael O'Sullivan with have gone on to win back to back.

It's Jazzy Matty who pips Unexpected Party on the line! What a finish.

Unexpected Party takes the lead as they take the turn for home...

Primoz may well be getting called up soon as it struggles badly at the back with three fences remaining.
Traprain Law leads the way but they're very well bunched.

Unexpected Party is travelling well on the outside in about third place with eight fences to go.
Western Zephyr takes the lead.

And we're off, for sure this time! Dancing On My Own jumps the first in front with everyone safely over.

Oh my goodness, they are supposed to come in at a controlled jog - that was a flat-out gallop.
16:40 Johnny Henderson Grand Annual Challenge Cup Handicap Chase (1m 7f)
And we're off! Oh, no we're not! A number of the horses were basically into a full gallop before the tape wasn't back. A false start is called.
Might take a while to call these back, some are a way down the track.

The horses walk very slowly towards the start as we're moments away from the start of this race.

Last year's winner, Unexpected Party, goes off favourite for this one at 5-1 with My Mate Mozzie being well backed into 11-2.
But, with 18 other runners in the field, your guess is as good as mine for who's going to claim the win here.

Now then, who fancies picking a winner in this race?! With 20 runners and no short-priced favourite, this race is wide open.
The team of Harry and Dan Skelton claimed the spoils last year with 12-1 shot Unexpected Party - who is one of the leading contenders in this year's edition.
Going off 9lb lighter is Jazzy Matty. All of you Matts out there might fancy a punt on this one.
He would be a poignant winner having triumphed in the Fred Winter Hurdle two years ago under Michael O’Sullivan, the Irish jockey who died in a fall last month.

The next race is fast upon us! With five minutes to go until 20 horses gallop around the famous course, let's take a look at a little preview.
