What was the largest field ever assembled for the Grand National?

Nowadays, the safety limit for the Grand National is 40 runners, but the largest field ever assembled was 66 in 1929. A photograph of the start shows the record number of starters stretched out, in one long line, across the entire width of the Aintree track.

The 1929 Grand National was also notable as the first renewal after the filling in of the ditch that had previously preceded the Canal Turn, which had been the site of the biggest pile-up in National history the previous year. Indeed, one of the horses that contributed to the melee, Easter Hero, was sent off clear favourite at 9/2 in 1929, despite carrying the welter burden of 12st 7lb. In any event, Easter Hero finished second, beaten 6 lengths, by Gregalach, who became the second 100/1 winner in the history of the Grand National and, remarkably, the second consecutive 100/1 winner after Tipperary Tim in 1929.

Of the 66 starters, nine horses – including three 200/1 outsiders, Melleray’s Belle, Delarue and Kilbairn – completed the course. There was, however, one casualty; Stort, another 200/1 outsider, nearly unseated rider at the first fence, did so at the third fence, fell, when loose, at the Canal Turn on the first circuit and fell again, fatally, at the twelfth fence.
