A teacher from Ambergate is beginning a unique world record attempt this weekend in aid of Children in Need
Richard Thoday will be trying to become the quickest person to ever travel from Lands' end to John O'groats... On a penny farthing.
The 55-year-old told us he's confident of beating the previous record set way back in the 1860's.
He said: "I'm reasonably confident, I wouldn't be taking it on if I wasn't. We're aiming for a Guinness record, the actual penny farthing record is just over five days but Guinness don't recognise that. They've set the standard at seven days so I could fail and still break the world record! But I'm aiming for the five-day record.
"It's very dangerous. You're high up, you're virtually on the point of balance so if anything goes wrong, you tent to go headfirst over the front of the bike, landing on your head. So we have to take this record very seriously."
