An eight-mile bicycle wheelie completed this week by Aaron Stannage, from Barnsley,
South Yorkshire is likely to earn the 14-year-old a place in the record books.
Cycling is not an extreme sport but most people use both wheels.
It will take Guinness World Records officials a few weeks to determine whether
Aaron has established a new record, but it is thought that this is the first
time anyone had attempted to wheelie the maximum distance within one hour.
During his record attempt, Aaron circled an indoor racing track more than
90 times while listening to his iPod to pass the time.
