A large group of riders were sent the wrong way by a marshal, leading to three colliding with a van at a junction, according to reports.
“Very tragic news. Our rider Stef Loos, a promising rider with the team, was the victim of a severe accident,” said team leader Jef Roberts.
“Together with two other riders, Stef was hit by a van and suffered serious injuries.”
Loos was taken to hospital where he later died, having suffered severe brain trauma and internal injuries.
