Cyclo-cross as it used to be back in 1960. Riders wading through rivers throwing their bikes in before them, washing their bikes in the river at the finish, cleaning themselves in a mucky bowl of water and brewing up afterwards on a meths stove - this video has it all.

The wonderful commentary is provided by Bill Baty, himself a winner of the GB National Amateur RR Champs in 1958 and 1959. The races just aren't like this any more! I particularly loved the BarnesBurY CC catering arrangements shown at 20:14.
