My first long distance tri! Heck, I haven't even completed an Olympic distance triathlon yet.
Despite this, I keep forgetting that I'm not racing this! I'm just doing it. I don't care if I even take 7 hours, though I don't think that'll be the case. If I can have my legs even after the long bike, I think I can even break 6 hours relatively easy. Unfortunately although a 56 mile bike is easy for me, it's not easy enough to run a 2 hour or sub 2 hour 1/2 marathon.
Just enjoy it Tim, just enjoy it!
