A male cyclist collapsed and died yesterday during the Prudential RideLondon-Surrey 100 mass participation event, organisers have confirmed. It’s the second year running the event launched in 2013 has been overshadowed by the death of a participant.

In a statement released yesterday evening, organisers said: “It is with deep sadness that we confirm the death of a participant in the Prudential RideLondon-Surrey 100 today.

“A 55-year-old man collapsed on the lower part of the ascent of Leith Hill and, although he received immediate medical attention and an air ambulance attended, the death was confirmed at the scene.

“Our immediate concern is for the family of the deceased and no further details will be released at this time. We would like to express our sincere condolences to his family and friends.”

After some of the 25,000 participants experienced delays of up to three quarters of an hour at the foot of the climb while the stricken cyclist received emergency treatment, riders were diverted away from Leith Hill through Abinger Hammer and Westcott.

Among those riding yesterday was Nicola Tait, who had been taking part in last year’s edition with boyfriend Kris Cook, 36, when he collapsed and died from an undiagnosed heart condition during a climb at Newlands Corner.

Nicola’s efforts have succeeded in raising around £3,500 for the charity, Cardiac Risk in the Young.
