The International Cycling Union says the mountain bike course at the Rio Olympics was not damaged by a wildfire.
The UCI says it checked the course Tuesday, and that it has "not suffered any damage which will affect the competition or the integrity of the venue."
National Olympic Committees also were being allowed to do their own inspections later Tuesday.
A wildfire Monday about 10 miles from the Olympic field hockey venue littered ash on the playing surface there. The mountain bike center is about 2 miles from that venue.
Practice on the mountain bike course is scheduled to begin Wednesday. The women's race will be held Saturday, with the men's race on Sunday.
