The mother of the cyclist Chris Boardman has been killed in a collision while cycling, her son has announced.

Carol Boardman, herself a former racing cyclist, died from injuries sustained in collision with a pick-up truck while out riding her bike in north Wales, the former Olympic cycling champion said.

“She leaves behind Keith, her partner for more than half a century, Lisa and I, and a large, loving family,” Boardman wrote in a tribute on Twitter. “We cannot yet conceive of a world without her in it. We love you Carol, may the wind be ever at your back.”

A spokesman for North Wales police said officers were called to the incident at shortly before 2pm on Saturday at a roundabout on Mold Road, Connah’s Quay, with the junction of Ffordd Llanarth. “The collision involved a white Mitsubishi L200 pick-up and a pedal cyclist,” the force said in a statement. “The cyclist was taken to hospital via ambulance with serious injuries, and sadly later died. We can confirm the name of the deceased as Carol Boardman.”

Chris Boardman, 47, who won a pursuit gold medal at the 1992 Olympics in Barcelona, said in a tribute his mother was “a stealth combatant and full of energy; mum was one of those individuals who could quietly turn anything into a contest”.

He added: “Our mum was the most positive outgoing person you could ever hope to meet and her generosity of spirit inspired everyone she met. Many of our childhood memories involve my mother and the outdoors, walking out over Hoylake sandbank, swimming in the deep gullies, or hunting for fossils on Llandegla Moor in north Wales. Wanting to share her passion for cycling, even well into her 70s, she often took groups of young novices out on their first forays into north Wales.”

North Wales police on Sunday renewed their appeal for anybody who may have witnessed the collision to contact officers by calling 101.
