When they get them all together, they will have a link on the 2013 site for the 2012 pictures. I know the event photographer is working hard to get everything up.
There are a bunch slowly coming in from different groups. Try googling "2012 Alberta Ride to Conquer Cancer", click "Images", then narrow to "Past Week". You'll find a number of pics from various sources.
There was a photographer taking pictures on one of the hill climbs on day 2 (it wasn't Edwin). He had an awesome backdrop as there was a valley behind the riders. I've searched around but couldn't find any of his pics or who he was. I know that's not too descriptive but hopefully this might ring a bell for someone who knows the photographer??
