By far the most colorful photo shoot we have been on. When we got this assignment all kinds of things went through my mind, the energy was high, and you could feel the excitement all around. We were shooting using camera settings I've never used before due to the amount of light, the constant movement of the runners, and the need for sharper focus for moving objects. The fun part was the constant moving in and around the paths of thousands of participants, it was crazy. And we learned a valuable lesson on 'how to keep your camera gear clean'! haha.
