A firefighter has pocketed £235,000 after betting just £34 on two separate internet accumulator bets.
Jason Evans, 34, from Coleford, Gloucs, scooped £153,476 by picking 11 winning horses and predicting two football results in an £11 accumulator bet.
He had also placed a £23 stake on nine races on the same day, netting him another £81,329.
Paddy Power, with whom he placed the bets, said the odds on winning each were about 10,000-1.
Mr Evans said: "I'm usually glued to the TV watching the racing, but because it was New Year's Eve I hadn't actually checked the results.
"Me and my wife were just about to walk out the door when the phone went and it was Paddy (Power) who told me I had won £250,000.
"I couldn't believe it. He said the accumulators I had done were amazing and I was their biggest ever UK winner.
"£235,000 isn't bad for a day's work is it?"
Mr Evans, who has an 18-month-old daughter called Mollie and works as a civilian firefighter at RAF Fairford, has been gambling since he was 19.
His biggest previous win was two years ago when he netted £18,000 on a horse racing bet.
Mr Evans plans to spend his winnings on paying off his mortgage and buying his 25-year-old wife Kelly a car.
