Ran indoors at the AFFC because of the cold (around 9 degrees) and the icy roads in our neighborhood. The track was fairly crowded this morning, but there was enough room to get around people. I caught up with and shadowed a couple of guys that wore matching Moab shirts for a couple of miles. I started to tire and fell off their pace just as they were ending. It really helps me to push the pace when I try to keep up with the faster runners that just jump in for a few miles. Felt good about the run, but I'm having a little soreness in my knee afterwards (usually after I sit down for a few minutes). It goes away before long, however. I need to get my mileage up in preparation for Boston, but I don't want to do it so fast that I get hurt. It's that old balancing act.
