Just to expand a bit on what I was getting at...

I have seen a lot of very average work from professional photographers covering racing events. They understandably want to have a sharp sellable image of most of the riders on any given day. This means making sure they have a high keeper rate by using fast shutter speeds to freeze the action.

Someone who may be on a track for the first time is quite happy just to have a photo to document the day of them being on a race track. A sharp freeze the action shot will do the job.

If you really want a spectacular photo of yourself on a track, then a friend with some good DSLR gear and a half decent eye concentrating particularly on you for a day could produce something you would be proud to frame and hang on the wall.
