Wed Night Worlds is a Short-Track style cross country mountain bike race series in Seattle. Courses are a mix of fast single track, paved roads and grass. We change up the course flow and distance week to week keeping laps at about 2-2.5mls. Approximate laps times vary from 12-18min. A typical winning time would be: Kids Race – 15/20min. Cat 4 – 30min. Cat 3 – 45min. Cat 2 – 45min. Cat 1 – 60min.

Within each race there are Men’s and Women’s Adult and U15 Boys and Girls Junior categories (There is no Cat 1 Junior category). Each category competes for the series overall or best 15 of 17 races. Points go 40 deep.
