Dark running

A 4am start for a trundle on a Saturday might not appeal to everyone, however it holds a certain fascination for me.
Quite surreal and somewhat of an out of body experience is how I would describe these 'dark' runs. It is good training for the North Face 100 in May.
My headlamp was offering two types of cast beam, as you can see below. If you look closely, you can see some of the trail in the natural moonlight photo, in fact once your eyes get used to it, you probably could run the trails without a head lamp (especially of there was a full moon).
