Project speed development continues, with some better results. I ran 5:30 officially (5:29 by my watch) at the Loudoun Street mile on Monday. It's a very slight PR, but I'll take it. It's improvement over last week.
Ironically, as part of Project Speed Development ("PSD" as we call it 'round these parts) I'm trying to slow other things down. Most significantly, my easy runs. I don't push them, but I think I could be running them even slower, resulting in better recovery. So I've reverted to an old trick - the HR monitor limit. Basically, any time I'm running easy by myself, I set the monitor to buzz me when I hit 150 BPM for my HR (that's pretty low for me). I'm also trying to back off some in workouts - using them as opportunities to practice good form, rather than hit a specific time. It's not about the split, but rather about whether I kept my body relaxed and ran with reasonable knee lift.
So, I'll take this path for a while, and see where it leaves me come fall (and serious racing).
