Carrie Ford is odds-on to get round on Forest Gunner in the John Smith's Grand National at Aintree next month.
Forest Gunner, who is trained by her husband Richard Ford, is a general 16-1 chance to win the £700,000 showpiece on April 9.
Mrs Ford, who will be the first woman to ride in the big race since Rosemary Henderson finished fifth on 100-1 outsider Fiddlers Pike in
1994. And VC Bet have offered some special bets on Mrs Ford and Forest Gunner in the Grand National - to complete the course 8-11; not to complete the course evens; to jump the first ten fences 1-3; to jump the first 20 fences 4-7; to jump all 30 fences 8-11.
She proved her readiness to partner Forest Gunner with a ride at Towcester yesterday on McCracken in the Speedy Hire plc Selling Hurdle.
As an amateur, Mrs Ford won the Fox Hunters' Chase on Forest Gunner over the daunting Aintree fences last year just weeks after giving birth to daughter Hannah.
Among Forest Gunner's rivals will be Joly Bey, who is still on course despite an unlucky run at Cheltenham last week. The eight-year-old was pulled up by his owner, amateur rider David Dunsdon, after being hampered in the William Hill Trophy Handicap Chase.
Joly Bey, who has 10st 7lb in the National, had put himself in the picture for Aintree with an impressive victory at Sandown Park in his previous race. Now trainer Nick Gifford just has to keep the gelding "ticking over" before a crack at the world's greatest steeplechase.
"He's as fit as a flea," said the Findon handler. "So far everything's in our favour. He's got a nice weight and David's really looking forward to riding him at Aintree."
Gifford will be bidding to emulate his father Josh, who trained Aldaniti to win an emotional Grand National in the hands of Bob Champion in 1981.
Ad Hoc will try and make it third time lucky in the race.
The Paul Nicholls-trained gelding was travelling strongly in Bindaree's Grand National in 2002 when he was brought down four fences from home.
The following year he was not out of it when he blundered and unseated Paul Carberry at the first ditch on the second circuit.
Ad Hoc has been allotted 10st 9lb in the April 9 showpiece and Barry Simpson, racing manager to owner Sir Robert Ogden, said: "He's in good form, he's schooled well and he's on target for the race. We are expecting him to go well - as well as you can with a bit of luck.
"If you look back through his record, he's a horse who has always performed better when he's carried less than 11st. He's not a robust, big, strong horse who carries big weights."
Riding arrangements for Ad Hoc at Aintree have yet to be finalised.
In contrast Monty's Pass has an excellent record over the big fences and his trainer Jimmy Mangan reported the gelding "every bit as good as he was last year" ahead of his third Grand National.
Monty's Pass won the race in 2003 and finished fourth last year. The 12-year-old has had four starts this season and on his most recent outing he was 10th of 16 in a hurdle race at Limerick.
"I was pleased with him that day," the County Corkbased handler said.
"There was talk after he ran last time that we might give him another run but there was nothing suitable and there was no need really.
"He's in great shape and I'll just keep him ticking over now before the National.
On a sad note, Earth Summit, the only horse to have completed the National treble, was put down today after being diagnosed with cancer.
The gelding, who was trained throughout his career by Nigel Twiston-Davies, won the Grand National in 1998 having landed the the Scottish and Welsh versions in 1994 and 1997 respectively.
A sprightly 17-year-old, Earth Summit started to lose condition about two weeks ago and following scans, was discovered to have cancer in both his liver and spleen.
He was put to sleep to avoid any suffering.
