long jumper three minis
JJ jumped six metres over the roofs of the cars at the event at Potters Fields, London.
The 2011 English champion, who has just moved to Newcastle to continue his training, admitted he was relieved to have completed the feat, which was to launch the Mini London 2012 Edition Models.
It comes after a successful year for the Olympic hopeful in which he achieved a personal best of 8.04 metres.
Speaking about his training for the Olympics, JJ said: It's going really well. I had a really good season this year.he athlete, from Hackney, east London, said: "Laughter is the best way to relax, I watch films like Don't Mess With The Zohan and motivational films in the morning then listen to my music later on as I head down to the track.
Hosting the event, British Olympian Steve Backley said the feat may have given JJ an insight into the pressure he'll feel if he makes the team next year.
