Well, it's official. I'm signed up for the Busselton half ironman (http://www.busseltonhalf.com/) and will be doing in on the 1st of May. I've started on a structured training program so that I'll hopefully be feeling a little more confident by the time the ironman comes round:

I'll try to get down to Busso in the next few weeks to have a look around the course.
