I can't make it, darnitall! I haven't yet run a real race BF and that would be a good one to try as a first.
As for being "BF friendly" - don't be too sure. 55 degrees is "cold" to native Floridians and so far the few cool morning runs I've had (45-48 degrees or so) have been very uncomfortable for the first mile or so! When you're only doing 3-4 miles that's kindof a bummer. I'm hoping to get used to it though!
My new wife and I will be participating in this event! We've been running in Vibrams for the past 6 months and can't wait to see what happens during an official race. I'll stop back after the event and let you know how it goes.
