Thanks for the info diane - this is one point that I am extremely concerned about. I absolutely hate cold weather. Being in NJ, that is bad enough. My worst nightmare is having to run the marathon in 30 degree weather. In the race packet, they say the weather can be anywhere from 30 to 80 degrees - real nice for planning. Then, they want us out there at 4:30 AM in the morning to start the run at 6:00. Well, since the snow is coming down outside right now, I guess whatever the weather is, it can't be any worse than here - right?
