Nice colourful image. It's hard to make out how sharp it is, because the image is small, but it seems pretty sharp indeed.
I would be tempted to crop it, so that the left hand side of the image is halway across the left hand riders face. This will match the right hand side of the image, and also crop our the support vehicle. Also, it will make the image appear 'full' of cyclists only. (IMHO only

)
Nice image, and good eye too see it in the first place!
