It's another major weekend for Newmarket as their autumn trio of Saturday's concludes with the Dewhurst Stakes and the Cesarewitch Handicap.
Saturday is Future Champions Day at Headquarters, with some quality two-year-old races ahead of the Dewhurst (3.00), while Chepstow's two-day meeting is a real starting point for the jumps season proper before Ffos Las hosts the Welsh Champion Hurdle on Sunday afternoon.
All the UK and Irish racing action can be followed via our live Sports Streaming service and here's our look ahead to the weekend's racing action.
The Group 1 Dewhurst Stakes (3.00) is the traditional end-of-term 2YO colts' championship at Newmarket and Saturday's race is packed with quality, despite Sakheer being ruled out by Roger Varian.
Aidan O'Brien's runner Aesop's Fables joins Marbaan for Charlie Fellowes in seeking to bounce back after disappointment for the pair in the Group 1 National Stakes at the Curragh four weeks ago.
Brian Meehan's Isaac Shelby is 2-2 and priced at 12/1 to add to his bet365 Superlative Stakes win here in July, while Charlie Appleby's Naval Power (7/2) won at Haydock last month despite traffic problems and is 4-4 now.
Also unbeaten is Sir Michael Stoute's Nostrum, the Kingman colt 11/8 to add to last month's Group 3 win at this venue. Chaldean won the Champagne Stakes at Doncaster impressively for Andrew Balding and is 4/1 to give Frankie Dettori a third Dewhurst win in five years.
It is of course Future Champions Day at Newmarket and there are some high-quality 2YO races as such.
Opening the card is the Group 3 Zetland Stakes (1.50) over a mile-and-a-quarter, where 11/10 Flying Honours will seek to rebound after a surprise defeat in the Royal Lodge over a mile here a fortnight ago. Charlie Appleby's son of Sea The Stars should relish this longer trip.
Mark Johnston has trained five winners of this contest and 11/2 Dear My Friend boasts fine credentials with his Listed run in France last time looking strong, while Ayr nursery winner Metal Merchant for Mick Channon could surprise a few with a big run at 25/1.
In the Autumn Stakes (2.25), Appleby's Silver Knott is 9/4 to recover from defeat behind Chaldean in the Champagne Stakes, while once-raced July Course maiden winner Epictetus is 5/2 to take this rise in class in his stride for the Gosden team and Dettori.
Karl Burke's Holloway Boy won the Chesham at Royal Ascot on debut in June and has two excellent seconds in as many starts since, chasing home Dewhurst favourite Nostrum here most recently. He's got leading form claims and is 11/4 under Clifford Lee.
The Cesarewitch (3.40) is one of the major handicaps of Newmarket's season and has become a plaything of the leading National Hunt trainers in recent times. Six of the last eight renewals have gone the way of yards more associated with the jumps, including three wins for Willie Mullins, a sequence halted last season when Buzz won for Nicky Henderson.
The Seven Barrows handler has 4/1 Ahorsewithnoname as a leading contender now, the mount of Ryan Moore, while Mullins has 12/1 Scaramanga and 10/1 Gibraltar in his team alongside 14/1 Baby Zeus - with champion jockey-elect William Buick on board the latter.
Arc-winning rider Luke Morris meanwhile is on 20/1 chance Call My Bluff for trainer Dominic Ffrench-Davis. He was third in last month's trial over course and distance and has run a big race since at Chester. His stamina is assured and a mark of 85 looks generous.
If stamina is the name of the game in the Cesarewitch, it's a different tale in York's feature Sprint Trophy Handicap (3.15) over six furlongs where the likeable Dakota Gold is 14/1 to register his seventh career win on the Knavesmire for Michael Dods.
He faces stiff competition from the likes of 7/1 Dusky Lord for Roger Varian, a decisive winner at Ascot last month, and Kevin Ryan's Bergerac at 14/1, winner of a major handicap at York in August - with Dakota Gold behind - and a close-up sixth since in the Ayr Gold Cup under a penalty.
Earlier at York, John and Thady Gosden will be hoping Saga can provide a Royal winner in the 1m2f handicap at 2.40 in the hands of Rab Havlin. He was an eye-catching Royal Ascot loser in the summer and now steps up in trip.
At Chepstow on Saturday afternoon there will be plenty of interest in McFabulous for champion trainer Paul Nicholls on his first foray over fences in the Listed Novices' Chase (2.52) over 2m3½f.
He was a dual Grade 2 winner over hurdles, including the bet365 Select Hurdle at Sandown in April when last out, and could be one to shine over the larger obstacles for the Ditcheat chief and Harry Cobden this season. He also has a pleasing record when returning from a break.
Meanwhile, in the Silver Trophy Handicap Hurdle (4.02), the Nicholls/Cobden alliance will look to Knappers Hill - winner of 4-7 over timber last season - in a quality event that also includes Dan Skelton's pair Proschema and West To The Bridge, Nicky Henderson's Broomfield Burg, Jonjo O'Neill's Zabeel Champion and Joe Tizzard's Bourbali, winner of his last three starts.
Last season was a standout one for Milton Harris and he'll be eager to see if regular hurdles scorer Appreciate can raise his game in the 4-Y-O Handicap Hurdle (4.37) where hat-trick seeking Bagheera Ginge is a key player for Nigel and Sam Twiston-Davies.
It's an important weekend for jumps fans with Chepstow's two-day meeting signalling a rise in quality for the National Hunt season and on Sunday attention switches to Ffos Las for the Welsh Champion Hurdle (3.10).
The New One, Silver Streak and Sceau Royal are amongst some recent quality winners and Tom Lacey's Glory And Fortune will attempt to become the first back-to-back winner since Potentate for Martin Pipe landed three-in-a-row in 1999.
It's a handicap so he's got top-weight of 11st 12lb under Stan Sheppard and they face six rivals.
Neil Mulholland's Milkwood and Harry Fry's improving Gin Coco - second at the Punchestown Festival when last spotted in the spring - are amongst the dangers while Hardy Du Seuil for Jamie Snowden could provide a Welsh winner.
