WATCH: Teenagers sledge down Thetford's historic Castle Hill
Could these teenagers be the next British Winter Olympic stars?
The group of four were seen braving the 25m high Castle Hill in Thetford with nothing more than a spongy mat acting as a sledge.
Neil Coomber-Webb, of Thetford Photography, captured the teenage bobsleigh hopefuls - who he said were around 17 - on Wednesday.
The 12th Century Castle Hill is thought to be the tallest motte in England and is a popular place for Thetford residents to gather on a snowy day.
Mr Coomber-Webb, who lives in Thetford, said: “I had taken a bit of a snow day with my kids and was taking photos.
“The group said they were going to the top and they went down once before and then they dragged the spongy mat back up there.”
He added: “I would not have tried it.”
