Now in its second year, the Tour of the Cornfields, based in South Cambridgeshire, is a cyclo-cross sportive that uses quiet lanes, by-ways and bridleways to offer a 58 mile ride with over 50% of it off-road.

While the organisers say it's ideal for cyclo-cross bikes, it's perfectly acceptable to ride it on a mountain bike. The terrain is mostly flat or undulating, injected with some short climbs, so it should suit riders of all abilities.

The organisers promise some new off-road zones, the return of classic sections and a new off-road signage system to improve navigation. The route follows a number of ancient tracks and roads, including the Harcamlow Way and the Icknield Way. Riders will cross through the site of the abandoned medieval village of Clopton.
