All proceeds from the MAGPAS Cambridge Cycle Challenge Sportive, set to take place this Sunday (May 19), will go to the MAGPAS Air Ambulance charity.

The sportive, which is new for 2013,  will offer 65 and 100-mile routes through the lanes and villages east of Cambridge.

Both routes start from the Lancaster Toyota showrooms in Cambridge, who are sponsoring the event, and will head out in an anti-clockwise direction through Linton and Saffron Walden to the first feed station.

The 65-mile course then takes in Balsham and Wickhambrook before returning to Cambridge, while the 100-mile option goes on to Mildenhall via Kedington and Stradishall, with another feed stop before making its way back to the finish.

Both courses are relatively flat but have several short, sharp climbs, however the biggest challenge of the day is likely to be the wind, which will either make for a fast ride or a tough day out.

Both routes will be fully signposted, timed, and will have well-stocked feed stations and mechanical back en-route as well as the start/finish courtesy of Ben Hayward Cycles. Free tea and coffee will be available before the start as well as a snack after for all finishers. A family ride will also take place, starting at 11am and taking in an course of between eight and ten miles.

Entry costs £25 for both the 65 and 100-mile routes. Enter online at www.wheelsinwheels.com
