A female cyclist has been left with serious injuries after a crash during a marathon charity ride.

The woman, in her 40s, was taking part in the 100-mile challenge on Sunday when she collided with a car in Cobham.

She suffered severe head, leg and face injuries after the smash with a Vauxhall Zafira in Halfpence Lane.

An off-duty surgeon treated the patient at the roadside at about 9am.

The orthopaedic specialist joined paramedics and air ambulance medics in tending to the woman before she was taken to London’s King’s College Hospital by road.

She has since been discharged from hospital and is said to be making good progress at home.

A spokesman for charity Action Medical Research, which organised the race, said: “The woman is still in some pain, but what looked potentially quite serious in the first instance is better than we anticipated.”

She would not confirm where the victim is from, but said most of the riders were from Tonbridge.

Hundreds of cyclists took part in the Castle Ride 100 event, which started and finished at Tonbridge Castle.
