Dig the clothes (gym shorts over tights! Sweatshirts! Hiking shoes with flat pedals!). Dig the glasses (gigantic, face-eating Oakleys!) And dig the bikes! Almost everyone in this footage is riding a mountain bike; the handful of folks who are riding road bikes are using flat mountain bars. It was a different time for sure. Also a treat is seeing some older race venues that don't get used now, like Pier Park in Portland and Willamette Mission Park in Salem.
Some things about 'cross have changed, and as this video shows, some have not. Enjoy.
