A cyclist taking part in yesterday's Prudential RideLondon-Surrey 100 has died following a cardiac arrest during the event.
Organisers confirmed his identity as Nigel Buchan-Swanson, aged 69, who was married with three children and six grandchildren and lived in Chichester, West Sussex.
They said the cardiac arrest happened at Ockley Road around 56 miles into the route.
Mr Buchan-Swanson died despite the efforts of other cyclists and medical personnel at the scene.
His wife Deborah said: “Nigel was a much loved husband, father and grandfather. He was a very experienced cyclist and died doing something he loved.”
He had been raising money for Macmillan and his fundraising page can be found here.
Organisers added: "Everyone involved in Prudential RideLondon would like to express our sincere condolences to Nigel’s family and friends."
First held in 2013, there has been a fatality on the event most year's it has been run - unsurprising, given there are more than 25,000 participants - with cardiac arrest the most common cause of death.
