The first half has lots of ups, downs and curves. Road has a slant in places. Run the tangent if you can. The 1st part of the second half was awesome downhill! Last few miles were flat, city miles. Cars were close and traffic was not controlled at some areas. It was difficult to pass the slower half marathoners in the closing miles on the narrow shoulder. Loved the finish! You could see it from a great distance. The volunteers were awesome as were the aid stations, bus, medal, shirt, organization. Mt Charleston continues to be my favorite over Big Bear & Revel Rockies.
