Ouch!

Today I thought I just didn't have it in the legs. I got dropped pretty early on in the Sea Otter Pro NRC circuit race and rode about half the race with other guys who fell off the pace of the front group. You never can feel too bad about yourself in this situation when you are riding with guys from bigger pro teams.
At the time I pulled out of the race, I just happened to reach down and feel my front tire (force of habit, I guess), and I realized I only had 30-40 psi left in my tire (down from 120psi). I have no idea when this puncture happened--maybe it was a minute earlier, but maybe it happened at the start of the race.
Before the start of the race, Laguna Seca was getting a lot of rain, and the start of the race ended up getting postponed an hour and a half. With the rain came sand and rocks from the sides of the race track, leaving a bit of debris on the track, probably resulting in my flat tire.
I've got one more race to do here at Sea Otter, and one last chance for redemption. Today is the mountain bike cross country event, one that I have done seven years in a row. Here's to hoping...
