If you're a keen mountain biker or a stupidly-enthusiastic photographer in the north of Scotland then chances are you'll be needing a good night's sleep tonight, as no doubt you'll have been getting plenty of exercise at the 24-hour Strathpuffer mountain biking race.

Here are a few of the photos I did for tomorrow's Press & Journal, all of them using a combination of ambient light and subtle flash light to create a slightly surreal but still fairly natural look.

How's this for a close-up action shot? It's wide angle @ 24mm, not telephoto.

That bony fellow on the right of this photo is Bill the Biker, a skeleton made of bicycle parts that lives about a mile from the end of the course. I was absolutely shattered after walking to the location with all my gear to get this photo, and the only really good angle had a vehicle parked in the background so I had to settle for this less interesting angle.
