Well, it seems I was right. I was able to knock off over 3 seconds from my best time last year. Granted, the course isn't identical to the last one, but it's close.
I don't think I was at my fastest yesterday. All of us only got to walk the course once, so I spent three runs just figuring it out. Everybody was off-course - it was a total mess. This was right after they got done pounding into our heads that we should walk it 3-5 times.
