I didn't take many shots, I was in awe of the riders!
The finale was a race between three riders; this young man, his father and a young blonde lady.
How they didn't crash I'll never know, they were so close at times.

Strange - I read an article about how few of these are left, and I thought about how to photograph it. I think you've made a good job here. I suppose two options would be to frame/crop tighter and/or to pan and create an effect of speed. Hardly easy conditions to photograph under though!
