Don't forget a multi tool for that matter, I've had a seat slip and go vertical during an off-road tri and thank god I had just thrown on my usual seat bag that had one in it. My thoughts on this, and we are about the same size, that the pound or two of equipment to carry around is a lot better than having to walk my bike.
I forgot to mention, for your first tri, have fun.
