The Sportive Cycling event 2013. To search by race number, click on SEARCH at the bottom of this page, and type 13SSA*** (where *** is your race number). e.g. 13SSA015 would bring up racer 15's images. Under 16's riders can be found with the code 13SSAU**
This is actually really impressive than anything I have seen recently. It is looking much more interesting due to the fact that it would be rare that you would have even seen such a different set of pictures lately.
