The theme for this year's race (and in hand its race merch) are retro mickey and retro disneyland logos. I saw people standing in line with 4 or more shirts/jackets. And others were off to the side taking multiple pictures to send to friends/family who couldn't make it to the expo on time. I had picked up so many things but settled for a long sleeve t-shirt that said "I'm Only Half Crazy. 13.1. Disneyland Half Marathon 2012". There were a couple items I noticed that were running out of stock, but hopefully they will restock them for the influx of 1/2 marathon runners tomorrow afternoon.
I also noticed a drastic increase in coast-to-coast merchandise for you overachieving and well-traveled runners. However, they are very generic with a 2012 slapped on them.
