The Annadel XC race up in Santa Rosa on August 16th is one of the best XC races around. I highly recommend it. The start is in downtown SR and there is a neutral rollout through town behind a police cruiser. The course is mostly singletrack with some fireroads and a decent amount of climbing. It’s been a couple of years and there could be some changes, but I remember a fun, interesting course, that isn’t too technical.
