The swim was the worst I've ever been in. Pretty much just had the shit kicked and punched out of me all the way round. I'd swim wide if I did it again, I thought it was bloody dangerous to be honest.
I loved the bike. Make sure you get a good look at the scenery. The long descent at the end can be taken pretty fast as long as you pay good attention to the hair pins and you're not in the middle of a storm, I went down at about 8mph wondering if I was getting hypothermia
The run ... 3 miles out, 3 miles back, repeat a few times, you can see the far end from the start and the start from the the far end and it looks a bloody long way!
