The Five Live selection is One Way in the 1400 at Wetherby (all times GMT).
The ante-post gamble continues on the Irish-trained Nil Desperadum for Saturday's Hennessy Gold Cup.
His inexperience over fences does not seem to be deterring punters who have backed the horse from 16/1 to less than half that price.
Provided top weight First Gold stands his ground Nil Desperadum has only 10st 8Ib on his back.
Mick Fitzgerald has been booked to ride the gamble.
Wednesday's racing takes place at Wetherby, Chepstow and Lingfield Park.
Tony McCoy makes a quicker than anticipated return to the saddle at Wetherby, where the ground is good to soft.
The champion jockey dislocated his right thumb at Folkestone last Monday and was expected to be sidelined for up to a month.
McCoy rides Ursis in the 1325 and She's No Muppet in the 1540.
The latter has won her only race and will start favourite to maintain her unbeaten record.
The ground at Lingfield is officially heavy with soft patches.
Decent novice hurdler Trabolgan makes his chasing debut in the 1445 and has been showing plenty of dash on the schooling ground at home.
It is soft with heavy patches at Chepstow where 2002 Hennessy winner Be My Royal makes a surprise come back in the 1445 after being retired because of injury.
The best bet of the day is One Way in the 1400 at Wetherby.
The horse is only seven years old and seems to be improving with each run.
Top jockey Graham Lee takes the ride.
