Darren Latter, who works in the Brooks Bros (UK) Ltd Danbury machining sales office, has been a competitive runner for seven years but this was by far the biggest challenge he had undertaken.
Half way into the race he was doing well: 9 hours 32 minutes and placed 10th. Then, as day turned to night things changed.
"I really felt like giving up at the 76 mile Aid Station 8. I tried to eat what I could but felt very sick," he said. "The temperature was now at minus 1 but felt colder due to the wind chill factor."
Colleague Keith Lovell joined him for the final 20 miles but Mr Latter had to dig deep to cover the final 10.
"I had to be helped to put on some more layers, as I could not do it for myself. I felt sick but managed some soup and coffee."
After 21 hours 24 minutes and 55 seconds he finished and was greeted by enthusiastic volunteers and well-wishers.
"I had a hot cup of tea and the best looking bacon sandwich that you could possibly wish for after such a night, but I still felt ill so Keith ended up having two!"
Of the 165 people who started the race, 90 completed the course and Mr Latter finished in 12th place.
