We went and checked out the ogden Sprints on Saturday night. It was a cool event with local hip hop/rock band and a great turn out of all sorts of riders. It was put on by Skyline Cycle in Ogden. This is a cool event for winter activities in the biking community.
Basically two people go head to head and there is a screen on to see who wins first. The bikes are single speed so your peddeling your arse off. Fun event with cool people.
