Great shots - would definately heed the advice of others and send them in (who to I would have no idea, but Im sure you would know).
Definately capturing the sport well, not just in terms of good image quality, but also in respect to getting the timing right in respect to the speed and daring of those bikers.
Also whats the worst that can happen - they dont use them, but if they do its adding another string to your bow
Nice work
