Liam Treadwell won on Mon Mome despite odds of 100-1
A man who put a total bet of £30 on the top three horses in the Grand National has won £65,000.
Jason Darmody, from Swindon, selected three horses to finish in the top four of the race.
Bookmakers William Hill said the win, which had an 11,848-to-one chance of coming in, was the biggest the company was aware of for this year's National.
He backed Mon Mome, Comply or Die and My Will, which finished first, second and third respectively.
"It seemed like an age before it flashed on the screen and I kept looking at my ticket," Mr Darmody said.
"I was looking at the screen then went, 'aargh I've won'."
The lucky gambler said he had gone to a party to watch the race.
"I knew I had the winner but I didn't know who came second and third," he said.
'Really big'
Mr Darmody telephoned a friend, who he said knew more about gambling.
He told him he believed Mr Darmody had won anything up to £100,000.
"I stood in the queue at the bookies and when I got to the front the man said 'this is really really big'," he said.
The manager of the shop asked him to step to one side.
"I thought, 'oh no don't say I've filled the form out wrong'," said Mr Darmody.
"He said if a race is more than 1.1 miles long they pay an extra 10%.
"I didn't sleep for a couple of days afterwards."
The horse Mon Mome won the Grand National on Saturday despite having odds of 100-1.
