It's hard to tell if this is from 1950 or 1960 but it doesn't really matter. This is total bad ass cross racing. Can you imagine chucking your bike as far across the water as you can and then jumping in?
The fellow talking about the riders sounds like he's from Scotland. He says that one racer used to be the head of the cheese counter at the co-op in Wallsend. Wallsend got its name from being at the end of Hadrian's Wall. Scotland is about 30 miles to the north of it so I'm guessing they're riding through some northern English countryside.
