Thanks, I did! You're right about the challenge of training for three different sports. It's also important to train the bike-run transition as it's harder than just running while tired.
At least here, the crowds are great, and there was no want for encouragement. It was a step up from marathons, and those are already memorably great! I remember a sign that said "you're 140.6% crazy!" I think calling a half 70.3% crazy is about right. Not totally crazy but up there.
