Week of preparation

As I am running a 5K race this Friday evening, and a 10K on Sunday, I am preparing this week to go hard in both races and shoot for new personal records. The 5K seems likelier to me, in some ways - my current record is 29:29, which I ran in the Holiday Hustle 5K in Dexter on December 13. And I have only run one 10K race since my accident - the 10K portion of the Dexter-Ann Arbor Run last June 1, which I did in 1:02:29. I'd love to break an hour, but don't know if that's feasible. However, I have run 10K under an hour a couple of times in training.
