I'm doing STP so hope to see you there! My friends and I are crazy enough to try it in one day though.At least you have the benefit of a previous STP under your belt. I'm sure you'll be fine and six months is more than enough to prepare. I've looked over the training schedule and it's very doable.
Maybe we should start an ongoing thread for those of us doing STP to track our training. Could be a fun way to stay motivated!
