I just got back from it, shorts and t-shirt are just fine. Since all the courses are different, it's kinda tough to compare times, but our pro-time was mid 31's, my time was 35.984, 471 points.
I improved about 2 seconds from my first run. If I could have kept doing it about 10-12 times, I'd have been even better.
It is a real good time though.
