Watch a Fast and Fun Preview of the Rio Olympics Mountain Bike Course

There hasn't been much good news out of Rio as Summer Olympics preparations heat up. But away from the polluted waters of Guanabara Bay, the mountain bike course is nearly complete and it looks ridiculously fun. 

Course designer Nick Floros strapped a GoPro to his helmet and released the footage from his ride so we can all take a peek at the three-mile dirt track, which features bridges, a tunnel, rocks, water, berms, and technical ascents. "The area chosen was very good to design for, as it has a natural variety of land types and many climbs and descents," Floros said in a press release. "We're going to have some different aspects, for example giant footprints around the course, and some parts based on the shapes we see around the city."

In the footage, Floros can be seen careening around U-turns, jumping boulders, and flying over ramps before braking to a halt and saying with surprise, "That was harder than I thought."

According to Games officials, the track at Deodoro Olympic Park is currently 80 percent complete. An MTB test event is slotted for October 11, and the men's and women's championship finals are scheduled for August 19, 2016.
