British Cycling - Responsible for majority of mass start races and cyclo-cross events

What's a mass start race? Usually 60 or so riders start off together and race over a set route. First over line at set distance wins. Simple!

What's a cyclo cross? Like a road race, but over a ploughed field! Good fun!
