Can you imagine running a course in Northern California and not have your legs aching from monster hills? That's exactly what's going to happen for all seven days of the California Orienteering Week, Mar 17 - 24. You don't want to miss this!
Tomorrow (Friday, March 9) is the last day for preregistration. After that, you can only sign up on the day of the event, and at considerably higher fees and with no pre-assigned start time. Don't procrastinate!
