Set back today. I started off up Jacobson and Trenton for a planned 16-miler, but about 12 minutes in my left achilles tightened up. I stopped and stretched, walked and tried to start again slowly, but this was enough to make me worried. I slowly jogged back, not feeling any better, and ended up walking a few blocks. No reason at that point to do anything worse to it. Hope to ice, stretch, etc.
So that's frustrating, in light of the progress and my hope for one longer run before the race. It did feel a little tight Thursday, so I'm not completely surprised by the decline. Back to the ice/stretch routine, we'll see what tomorrow brings. In any case I'm going into this marathon way undertrained, so I may as well take a shot at going in healthy.
