Course Maps

Saturday Course

Saturday will feature a clockwise version of this course. We’ve never raced this course iteration in a clockwise direction so this will be something new for everyone! We have made some minor tweaks to the course from the September edition to keep riders on their toes adding some challenging corners and grass. Already a challenging course, in this direction the climbs get very technical and may result in a few short run-ups depending on the weather!

Sunday Course

Sunday will feature a counter-clockwise version of this course. We have made some minor tweaks to the course from the September edition to keep riders on their toes adding some challenging corners and grass that should be extra fun in this direction. The pond section will remain technical off camber, tricky but ridable until it gets super greasy. Technical sections will get very slick if there’s any rain but could be ripping fast if the weather holds out through Sunday afternoon!

Bike wash, podums, and kiddo cross are located near the main gravel lot under the oak trees.
