Heini Rave submitted this unusual route (which is only a small portion of the Winterswijkse berg mountain bike course):
The Winterswijkse berg is a hill of 50 meters above sea level near Winterswijk. Because we have not much hills and mountains in the Netherlands, this is a place where many runners train and do competition who can make the fastest 1000 hm+ 1500 hm+ ..... The hill is 49 meters above sea level, and has a elevation [gain] on the highest point of 19 meters. But the north side has a elevation of 13 meters [over about 50m distance] but is the fastest side to make quick up and downs.
