Below is an aerial map of the event area and race course (view a larger version of the map in Google Maps). The basic course loop is about 1.1 mile long and features a short 60 ft climb along a smooth winding trail up the bluff (at the northernmost part of the course). The start loop (shown in orange) is all double-track road, which will allow racers to jockey for position and pass slower riders before hitting the singletrack (update 8/8: to simplify start logistics, we decided to scrap the gravel climb shown at the beginning of the course preview video). About 75% of the regular loop consist of fast, sweeping singletrack trails, including a fair amount of banked turns. As you can tell from the video, much of the singletrack is wide enough for passing, though we like to remind everyone to be courteous and safe whenever passing slower riders.
