Emergency 2018 Patapsco Valley 50k Venue Change

Due to upcoming weather conditions we've been forced to change the venue for this weekend's 2018 Patapsco 50K event. State Park policy states that if greater than 0.25” of rain falls within 24 hours of events scheduled to use the trails, that those events will not be allowed to proceed. Complete details of this change are available here.
