THE BIG NEWS:  The 2019 race (June 1) will start and finish at a new location!

The 2019 race will start and finish a few miles down County Highway 126 from Pine Valley at the intersection of Buffalo Creek Road/FS 543 and Highway 126.  The Buffalo Park Improvement Association (BPIA or "Bippy") is allowing us to start and finish at its Community Hall and to use their large field for parking.  In honor of BPIA, the new start/finish location is nicknamed "Bippy."
