Just finished my first tri as well.
I have done a few marathons, decided to try something new. Swimming was definitely my weakest sport... but I took the whole thing very conservatively, not knowing how I'd feel at the end. my time was 1:40, which I was happy with for my first time. My Transitions were terrible cause I don't know what I'm doing yet. I think I probably spent a total of 5 mins in transition.
I really need to beef up my swimming , hoping to do that over the next several months.
