Ian Jamieson and his colleagues from Team 101 are planning to set a world record for the longest distance jumped over a car using pro-jumps, a sort of hi-tech stilt.

The stilts are used in a form of extreme sport, where people strap them on and the springs allow them to run at superfast speeds and jump high into the air.

Ian, a 20 year old web designer from Denmead, became involved in pro-jumping after having a go on a pair.

He said: 'My friend brought them down to Southsea Common one day. I tried them out and they were great, so I went and bought a pair.'

Team 101 were originally a group of free runners, who approached Ian after seeing videos of him free running.

The group, which is sponsored by Pro-Jump that makes the stilts, will also be appearing on Sky One's Guinness World Records Smashed when they will attempt to set a world record in front of a live audience – Ian and Team 101 will have a 15-metre run up before attempting to jump as far as they can over a stationary car.

They will be setting a world record as they don't believe such a jump has been recorded before.

'Originally they wanted to see how many continuous back flips we could do, but the studio wasn't big enough, so we are jumping over a car instead,' said Ian.

Ian says he has never seriously hurt himself, even when he started using pro-jumps for the first time.

He said: 'Luckily I've never broken a bone. The worse I've done is cut myself falling but it's fine the next day.'

The team are well known in the pro-jumping world, both in England and abroad. Ian and team-mate John recently went to Spain to film an advert for a Spanish drinks firm.

'There's good money in this work,' Ian said. 'Eventually we want to get enough money, that we can do pro-jumping full time.

'Anyone of any age can pro-jump and it doesn't take long to learn.'
