Transitioning to a training schedule

I did 5.2 miles yesterday, but today was hard to get up in the morning. Sleepy! I did manage to get out, and do a 5k, but I also started to add a bit of the speed intervals from the runningworld half marathon training schedule. The full training schedule, that I will try to follow as closely as I can (I can't always control which days I can run), I am posting here.
