I'm in. Am/was hoping to go sub 4:30 for the first time on this course but I've got Raynaud's syndrome and a low temp of high 40's at the start isn't really something I'm thrilled about. Assuming the swim goes ok, I'll likely be spending time in transition putting arm warmers and gloves on to completely undo the aero gains I've worked for. Crossing fingers that the low temp is about 10° warmer.
