Question

What are the longest odd's for a grand national winner?

Answer 1

100/1 is the longest odds for a winner so far.

Answer 2

Longest odds winner - Tipperary Tim (1928), Gregalach (1929), Caughoo (1947), Foinavon (1967), all 100/1

Answer 3

Remember that the last 100-1 shot was Foinavon in 1967. My brother gave me Ten Shilling each way to put on it. I nearly didn't. Thankfully I did and for those days,he won a lot of money. (I was earning £40 a month! and ten shillings each way was £1)
