In answer to Bike Chick's question, no, I didn't have trouble keeping my shoes on (but I wear VFFs, which are a lot easier to keep on than sneakers would be)--just had trouble staying upright because I was sliding everywhere! It's easier to run on ice than to run in mud like that. Crankin, I hope your friend wasn't one of the people around me at the beginning that had to hear me yell "stay the h*ll away from me" because I was so scared that they would end up on top of me in a collision...not my best moment!
