The XC course for the Sea Otter classic has recently been posted. They have changed it a lot this year and I don't think it is for the better. Beginners and Sport classes are doing a shorter 2 loop course that doesn't include Couch Canyon or the Goat trail. It appears to be mainly fire roads and a small amount of single track. BTW, the expert class does include Couch and the Goat trail, downside is that is about 30 miles...I'm not ready for a 30 mile XC race just to ride the "fun" trails.
