Enjoyed that, i've been doing a bit of that self filming stuff myself, this was my effort last week.

If i could offer any constructive criticism, a proper tripod would help so that all the shots aren't looking up from the ground, and try and take the camera further away from the trail so we can see you riding for longer. I've just bought a panasonic TS1 with HD video for helmet cam/bike filming duties, its sitting at my desk now and i still have 3 hours before i can get home and play with it :x
