Looking forward to next week! I'm doing the 5 and 10, and DH is doing the Rebel Challenge.
I'm going as Hoth Leia, with white capris, white short-sleeved shirt, and white fleece vest. I imagine the vest will come off during the first mile, but that's fine. DH hasn't totally worked out his idea yet but I'm sure he'll come up with something. Nothing like waiting until the last minute!
