I haven't run much since the last half and honestly, I am not very worried about the upcoming one n a week. I figure if it is tough, I'll walk. However, I must admit, I am competitive enough (with myself) to really want to beat my last time. I've only run twice this week, and only 5 miles each time.
I plan to try to do 5 again on Monday and then maybe just 2 on Wednesday. Then I'll just see how it goes next Saturday.
