Sleep-deprived Jimmy Burke was back at work yesterday - and already planning his next physical challenge.

Less than 48 hours after he was booted off reality TV show Shattered, the 33-year-old youth worker was forging plans to complete the 99-mile South Downs Way.

Jimmy, who helps young people at Hove YMCA, said: "I've already done 33 miles of it with my girlfriend Lucy but we'd like to do the full thing.

"I like a challenge."

The trial of staying up for a week was not the first unusual test he has set himself.

Ex-soldier Jimmy, who lives in Kemp Town, has walked Hadrian's Wall on his own, which took four days.

He has also climbed volcanoes in Indonesia and Table Mountain in South Africa and stayed up for three days digging a trench in Germany when he was in the Army.

He said: "They were all very challenging but nothing was quite like Shattered."

In the Channel 4 challenge, contestants competed for the £100,000 prize money by trying to stay awake for seven days.

After leaving the show on Friday evening Jimmy slept for nine hours. But the following night, despite the lack of sleep, he and the other contestants went out in London until 5am.

Despite not winning, he has no regrets.

He said: "It was a brilliant experience."

The ten initial contestants on the show were put through a series of endurance tests. Each day, one was eliminated.

Jimmy, whose previous jobs include working as a chef, a nightclub manager and a bingo club caller, was ousted after coming last in a reaction test.

The programme was won by trainee police officer Clare Southern, 19, from Dorset.

Other than being recognised in the street, Jimmy said last night his life was getting back to normal.

He said: "Psychiatrists say my brain chemistry will be disturbed by the lack of sleep and I might have mood swings, depression and cold sweats. But at the moment I feel fine."
