The rest of the day up until the race start was pretty uneventful. We got signed in, got our punch card, etc, walked about a mile of the track to check it out, and watched the pro race start. The main thing that had me worried was the narrow chute of the start. All the bikes lined in in rows, each row being flagged off at 1 minute intervals. So as many as 20+ riders all careening to the tree-line where they all had to funnel in between two big trees just 2 or 3 bikes wides was pretty harrowing. To make matters worse, going from the bright sunlight of the field into the darkness of the woods, there were even more trees just beyond the tree line in the middle of the trail you had to avoid, and just beyond those a slick mud hole to navigate - of course, all this while in a pack of 20+ riders, all of whom are trying to be in front.
So I had that to think about for several hours before my race started.
