Rio 2016 Olympics - The Rio Olympics road race course that cyclists will line up on this weekend is being described as difficult and dangerous.
The Nelson cyclist George Bennett said he can't believe authorities allowed the course to be signed off.
Bennett, who is fresh off the Tour de France, and Linda Villumsen will ride for New Zealand in their respective road races on Sunday and Monday.
Bennett was shocked when he first saw the course.
"I'm really surprised that someone signed off on a course this hard," he said.
"It blows my mind... it's going to devastate the field and there's not going to be so many finishes I don't think, but it's everything I like.
"It's hectic, it's crazy downhills, it's really really dangerous (in) a lot of the places.
"All the corners push you out and there's these pretty walled-off curbs and slippery roads, a bit of oil, things like that."
George Bennett's race gets underway at 12.30am on Sunday.
