Last night I ran 3 miles and the foot felt fine. So I was thinking today I would run another short run, probably 3 miles again, and then tomorrow do my week's long run: 8 miles. I had been aiming to do my long run today, but then several things impeded me. For one, I felt that one day of running was not enough to ease me back and go straight for the long run (granted, I did a lot of elliptical cross training this week, but it's not the same as running). But for another, I just didn't want to get up early this morning.
So, I'll just flip-flop the weekened training distances and then Monday I should be in good shape to resume my normal training schedule (if the foot is still feeling fine after the long run).
This is why I should NOT re-join a gym: I had a trial membership for 7 days, and how many of those days did I use it? 3. 3 days. There is good stuff at the gym, but I think my issue is just getting there. It's only 2 miles away, but for some reason, getting in the car and going there seems like so much more effort that lacing up my running shoes and heading out the door.
