SAFD: Also hate the cold - though I understand I'm in the minority here! So layers it will be. I'm going to have to do more shopping as I only have throw away layers for 2 days right now. The only tips I can think of as a regular winter runner (going to be heading for an outdoor run today - temperature is sitting right at the freezing mark) is don't forget to protect your extremities. Find a warm hat, gloves, etc. I'm going to do a rush order of cheap wool gloves from
amazon that I can toss.
Also - don't forget post race. While Disney usually hands out mylar blankets, you'll want to have something warm to throw on in your checked bag (another reason I hate cold races- I really don't like checking a bag). Even if you're feeling warm at the finish, your body temp will drop quickly during recovery. Have a hat, gloves, jacket available for after the race.
