This year was nothing short of freezing - but it is not the norm. The 3 other times I ran Disney I was more worried about overheating. My wife ran the 1/2 and it was sleeting, I may have complained more spectating :zipit: , I ran the full and thought I would drop layers as I ran, but ended up running covered like I was still in CT. Bring gear to be prepared, and we always hit a thrift store to score old sweat pants & long sleeve shirt that we throw away on the way to the start as it can get chilli at 4am in the staging area...great thing is any throw away stuff you ditch before the start all goes to charity. Be prepared with a little forethought and you'll be fine...but beware, as you say this is your first, these races are addictive!
