Tidal Bay and Long Run head a maximum field of 40 for the Crabbie's Grand National at Aintree on Saturday after all the leading fancies stood their ground at the final declaration stage.
The teenage Tidal Bay will carry top-weight of 11st 10lb in the hands of Sam Twiston-Davies, with Cheltenham Gold Cup and dual King George VI Chase hero Long Run next in on 11st 9lb under Sam Waley-Cohen.
Long Run's trainer Nicky Henderson also has Hennessy Gold Cup winner Triolo D'Alene, Hunt Ball and Shakalakaboomboom in contention as he aims to secure his first victory in the race.
Last year's third home Teaforthree heads the market for the world's most famous steeplechase for Welsh trainer Rebecca Curtis, with Nick Scholfield the man on board.
Perennial champion jockey Tony McCoy had to choose between the JP McManus-owned duo of Double Seven and Colbert Station and he has, as expected, sided with the first-named.
McManus' other possible Lost Glory was the only horse who was guaranteed a run to be taken out at the 48-hour stage.
Other leading contenders include Michael Scudamore's Monbeg Dude, the Willie Mullins-trained Prince De Beauchene and Balthazar King from Philip Hobbs' yard.
The 40th and final horse in the field is the David Pipe-trained Swing Bill, although there are four reserves.
Goonyella, Soll, Night In Milan and Minella For Value could potentially get a run if there are withdrawals from the final 40 before a deadline of 9am on Friday.
