Every year, the World Mountain Biking Bog Snorkelling Championship is held in Britains smallest town of Llanwrtyd Wells in Wales. (no idea how you say that).
The entrants power through a 125 foot long bog trench on a special bike that has its tyres filled with lead and water.
This year Bryan Evans won the coveted title and a tankard for completing the stretch in 1m 1s.
He added: “It’s very murky and you can’t see much in the bog. It doesn’t taste too good either!
“The bog smells a bit as well so I probably won’t see my ’missus’ for the next few days. I don’t think anybody else will want to come near me for the next few days.”
Emma Wood was the fastest lady at a slow 4m 27s.
Sounds like a mans sport to me!
