As a matter of interest, are there any other mass-participation sporting events that take place in black and white when men were men etc? Football matches in baggy shorts and a heavy ball, golf tournaments with plus-fours and Mashie Niblicks? That sort of thing.
Just teasing. The Eroica has always appealed as it's a civilised step away from the general willy-waving, ten-bob bikes, two-bob legs type Sportive/Fondos.
