If you need a little Fall inspiration here is a link to some nice videos done by the manager of Vaajakosken Terä of the second and third night orienteering races in the Kurkocup (King's Cup) in Central Finland.
the address is:

then scroll down to "Kurkovideo isompi" (or for a cut down verson "Kurkovideo pienempi") for the race a week ago and the second video from yesterday, in very different conditions as you will see, is under "Kurkovideo Iceage". What do you think, isn't there something sublime about the bodies with lamps for heads sprinting into the forest? Music is not bad either.
