Always found that strange as well. I've always loved being a runner in Seattle because its generally cool, cloudy, and often light rain. To me that's the perfect weather for a run since it prevents you from overheating or dehydrating as quickly, and, in my experience, the sun tires you out much quicker. I've always been confused about the fact that you see by far the most people out running on a hot, sunny day. Every one of them seems to be sweating bullets.
