A teenager who's mad about motorcycles has beaten experienced riders to one of the top slots in a Supercross event.

Jack Grover, 15, was competing for the first time in the sixth Annual British International Supercross Competition at Sheffield Arena, which involves riding round a track and navigating a series of difficult jumps.

He finished second.

The active teenager has been taking part in motocross since he was ten and has only just decided to have a go at Supercross.

Jack, of Southwater Street, Southwater, near Horsham, said: "I felt on top of the world, the adrenaline was pumping. It was amazing.

"There are three qualifying heats. I won the third and then came second in the final.

"Supercross is a progression from motocross. It is a lot more technical. There are a lot of jumps to go over, some are quite high and sometimes you have to jump two or three in a row."

Jack, who is hoping to go on to become a professional rider, thanked his parents for supporting him, Sussex Sports Motorcycles in Burgess Hill, for sponsoring him and especially his little brother Ryan, 12, who gave up motocross so the family could afford to let Jack pursue his dream of becoming a champion at Supercross.

Jack, who goes to Tandbridge School in Horsham, said: "I train at the gym but in summer I do try to get out one night a week. When I come home from school I do half an hour on the push bike and stretching every night."

His dad, Dave, 37, who gave up motocross about five years ago, is proud of his son.

He said: "It is very exciting to watch in the arena when all of a sudden the riders are head-height as they go over the jumps.

"He is very dedicated. I am very proud of him.

"The jumps are so steep and some people are daunted by them but he isn't. His mum Belinda said watching him was better than giving birth to him."
