I am 22 years old so I'll assume that it's not an age thing, but I am going to try a different schedule for the next couple of weeks. Road riding instead of mountain biking (it rained over the weekend so the trails are wet anyways), and I am going to do a better streching routine. I'm also going to do a different type of climbing so that I'm not carrying as much gear while I'm hiking.

Terry - I think you're right, pay more attention to what I am doing and I should figure out what the problem is.
