A silver tankard stuffed with lettuce was the prize at Norfolk, England's snail racing championship, with more than 150 gastropods in competition.

The snails are placed on a special damp cloth marked with three concentric circles and the creatures race 13 inches (33 cm) to the outer ring.

"We take this seriously," snail racer John McClean told Reuters.

"We have got training slopes. We look at diet, we are drug compliant as well. It is the whole thing when you look at elite sports."
