I saw my first dog sled race! It was more of a warm up than a race. A 7 mile loop around the mountain side. It took about an hour and I stood there in a foot of snow waiting in the cool sunshine to see their return. The teams take off one by one so the dogs don't get tangled and play with one another. They all come back one by one, winners are decided by the time it took them. Each team has a timer so it isn't really a sprint at the end or anything.
