Bike experts were on hand at a popular park in a bid to reduce the number of accidents on Royal Borough roads.
As part of a three week campaign aimed at lorry drivers and cyclists, the Kensington and Chelsea Council gave bike riders a rare opportunity to see the road from a HGV driver's viewpoint and learn about the dangers in passing big vehicles on the left hand side.
The awareness event was held on Wednesday at the entrance to Holland Park, Kensington High Street. Officers from the police's Campden safer neighbourhoods team also took part.
The Royal Borough's cycling champion, cllr Maighread Condon-Simmonds, said: "Even the most road-aware cyclist will probably never have seen what a cyclist looks like in the mirror of a HGV and more importantly when they don't appear in the mirror. This event gave cyclists a chance to brush up on the basic rules of the road and see things from a different perspective. I'm also very pleased to hear that the campaign will also encourage lorry drivers to pay special attention to cyclists."
The campaign follows a series of fatal accidents throughout the capital, including the death of Victoria Buchanan.
She died on October 17 last year after being in collision with his HGV at the corner of Fulham Road and Beaufort Street, Chelsea.
Ms Buchanan, who was head of operations at the Chelsea FC's pitch owners club and engaged to be married, died of multiple injuries at the scene.
