Spring Heeled and Cause of Causes to battle it out...
Cause of Causes looks dangerous but Indian Castle is making a move to challenge Spring Heeled.
And now Buddy Bolero is out of the race.
Still Spring Heeled continues to look dominant but Indian Castle is not far away either. Tabhachtach is out of the race after unseating his jockey.
The field is really strung out, with Spring Heeled happy to take control from the front. Twirling Magnet is travelling well too.
Spring Heeled and Buddy Bolero have opened up a lead of around seven lengths.
It was a strange, old start with some horses being left behind at the back. Spring Heeled and Buddy Bolero head for the front.
The sun is shining now as the Fulke Walwyn Kim Muir Challenge Cup gets under way.
The crowd's have certainly enjoyed some great entertainment on the third day of the Festival. I wonder how many managed to stay clear of Big Buck's and Annie Power, instead backing eventual World Hurdle winner More Of That?
Shall we have a go at picking a winner in the next race at 16:40? Go on then...
First of all, Indian Castle is the favourite but it's the second-favourite Cause of Causes who catches the eye. Nina Carberry is on board the six-year-old which relishes the longer distances. Top amateur jockey Robbie McNamara will hope to impress on 12-1 shot Spring Heeled, which last won at Killarney in August.

"End of an era at Cheltenham. Paul Nicholls with Big Buck's - four-time World Hurdle winner's retirement lap of honour."
BBC Radio 5 live
Former Manchester United manager Sir Alex Ferguson: "I was over at Michael Owen's stables and the intention was to be here by 10am, but I only just made it here. Everyone in racing loves Cheltenham - it's the be all and end all.
"I've been so busy recently, travelling all of the world. And I'm an ambassador for Unicef and United and at the Harvard Business School. I teach on a course of business and leadership. I've had one winner today - Fingal Bay. I saw it from Michael Owen's office."
Our next race is the Fulke Walwyn Kim Muir Challenge Cup. Try saying that quickly! Just before we look at the contenders in that race, our radio colleagues have caught up with a certain former Manchester United manager...

Tom Scudamore, jockey on board Ballynagour: "This is nuts, isn't it? Cor blimey! It's so special, and I haven't had enough of this Festival yet."
BBC Radio 5 live sports extra
Ballynagour owner Allan Stennett: "That was brilliant! We actually won this race two years ago. I'm from Sheffield originally and we make nuts and bolts for a living for the oil and gas industry. I have to say, Tom Scudamore is riding so well at the moment. And it gets better - I'm getting married on Monday!"
BBC Radio 5 live sports extra
Luke Harvey, racing commentator at Cheltenham: "The stable have been so shrewd, ironing out Ballynagour's flaws, bringing him here under the radar and he has run double over the rest here."
That's a decent-priced winner if anybody was on that?
1. Ballynagour (T Scudamore) 12-1
2. Colour Squadron (A P McCoy) 5-1 Fav
3. Tatenen (A Thornton) 33-1
4. Johns Spirit (R P McLernon) 9-1
What a victory for Ballynagour, who wins the Byrne Group Plate by around seven lengths. That was some serious pace in the final straight from the David Pipe-trained horse.
