After a quick chat with her and her classmates I continued on and made it to North Av. it pretty decent time. I was feeling good and the weather was perfect, so I decided to continue south from North Av. on a surface street that paralelles the river just to see if I could pick up the trail again, which I did pretty quickly. It was a pretty tight single track, but it was a trail. I came to a rail road bridge that was still too muddy to pass underneath so I carried the bike up and over and then continued riding. Then I crossed Chicago Av and continued south but not very far past that point I just completely lost the trail. The river has been well over its banks during the winter and either I was following the wrong path to begin with, or the trail has just been washed clear. I didn't feel right blazing a new trail, the ground was still fairly soft, and it occurred to me that had a pretty good distance to go to get back to the car. So I felt it was a good time to turn back. I hadn't brought any snacks (mistake #1) and I had finished off about 1/2 my water bottle by this time. I only carry one bottle on the mountain bike, but it is a big honkin' thing so I thought I still had enough to get by (mistake #2). Back at North Av, it occurred to me that I could stop at the drug store that is right nearby, and grab a snack and refill the water bottle, but as I was still feeling pretty good, I just continued on (mistake #3). By the time I was about half way back to the car I was getting really tired. And at about 3/4ths of the way I was really, really tired and out of water. A whole new kind of ache had started in my legs. Rather than just one or two paticular muscle groups being sore, my whole legs were aching. I have never wanted to just lay down on the ground and take a little siesta so badly in my life. I had tossed an apple in the car when I left the house that morning, so I just kept thinking about how delicious it was going to taste, and I just kept pedalling. Many explitives were uttered along the way, but I made it back to the car. And that apple was amazing. I sat in the car and devoured it like a ravenous ferrel dog and while I did so, my legs cramped up like nobody's business. I managed to waddle around well enough to get the bike loaded back onto the Subaru and headed for home. Back at the house I constructed, and feasted on, a most prodigious sandwich and then went ahead and grabbed that siesta I had been fantasizing about earlier. The whole ride only ended up being 26 miles, but I was far more tired than I had been after my longest road bike ride last season. Poor preparation.
Here are a couple pictures I've taken with my cell phone while riding this trail:
