DRIVERS are being urged to watch out for nearly 500 cyclists on Dorset’s roads this Sunday as the annual Macmillan Dorset Bike Ride takes place. 

On July 3, riders will be taking to Dorset’s roads to raise funds for Macmillan Cancer Support. 

Cycliists will leave Corfe Mullen recreation ground between 8am and 10pm and head towards Wimborne before returning throughout the day via Lytchett Matravers.

Motorists are being asked to be particularly vigilant as cyclists cross the main roads - especially at Red Post and the A350 at Lytchett Matravers. 

Riders will be offered a choice of four distances, including 38, 48, 63 and 100 miles, with cyclists riding along the Stour Valley, Winterbourne Valley and to some famous Dorset landmarks such as Bulbarrow Hill and Milton Abbas. 

The event will also see a man cycling on his 80th birthday. 

Barrie Corbin, a Macmillan Bike Ride volunteer, will be taking part in his 34th bike ride since his first ride in 1989.
