Glenwood canyon is a deep canyon formed by the Colorado River in western Colorado. I-70 is a major east-west US interstate highway that is routed through the canyon. Some spectacular engineering was used to preserve the environment and fit a four lane highway into a small space. A bike path was developed as part of the project and this ride follows the path from west to east through the canyon. In 2020 there was a large wildfire that started in the canyon, you can see burned sections along the ride.
