Four-time Paris-Roubaix winner and three-time Tour of Flanders winner Tom Boonen narrowly escaped injury after a motor racing crash in the final of the Belcar Endurance Championship at the TT Circuit Assen in the Netherlands on Sunday.

Boonen retired from professional cycling in April 2017, a day after finishing 13th in Paris-Roubaix, and made his motor racing debut in July of that year.

The day before his crash, he took his first win in the CN Prototype division of the Supercar Benelux Challenge at the same TT Circuit Assen on Saturday, posting a joyous photo on Instagram wearing his racing kit. But during Saturday's bell car race, Boonen told Belgian television station VTM how German driver Kenneth Heyer's Mercedes AMG-GT landed just inches from the head of his Norma M20FC.

"I passed Kenneth, but he was too fast and hit me," Boonen told VTM, according to hln.be. 'That resulted in a big crash. [I don't think he saw me. The car fell on top of my car, 10 centimeters from my head, and I was really very lucky," he said of the crash, which occurred when both cars were traveling at more than 200 km/h, according to Het Laatste Nieuws.
