Unfortunately this meant that the runners had to tackle a steep climb on each of the one-mile laps, made more difficult by a bitterly cold headwind which hit the runners at the hill.
Mangan, as world indoor record holder, had been invited to run the race and had been assured that the winner would receive a cheque for $3,000.
Although others, including three-time Spartathlon winner Scott Jurek, dropped out, Mangan pressed on to win the 48-hour race with a total distance of 203.984 miles, not bad considering the conditions.
Despite his clear victory, at the prizegiving, he was told that he had not reached the minimum distance of 250 miles required to take the cheque.
"The course was very hilly, contrary to what I was advised. It would have been just about impossible for anyone to run 250 miles," he said.
"Plus this requirement was never mentioned to me or any of the other runners before the race," added Mangan, who is lodging an official complaint with the International Association of Ultra Runners.
