Sleepy, knackered or hungry?

15M - double; recovery run & mile rep session
5M am recovery run at ~6.15min/M
10M pm incl 6x1M at 5.00-5.15min/M off 2min jog recovery

It's confusing sometimes, the difference between sleepy tired, physically tired and just plain hungry.

I fitted in a fairly brisk recovery run this morning around the park so that I could make it to a morning meeting on time. I then spent the the day stuffing my face cos I was starving and feeling knackered - as if I was going to be incapable of a proper session this evening. In fact, I think I'm just sleepy. Too many early mornings in a row.

And I felt great once I had jogged down to the river. I left my stuff at work and put in some really good miles along the river. I only had my stopwatch, so I ran 5.15 minute bursts rather than measured miles. It let me concentrate on finding a good rhythm rather than stressing about every last second (it was pretty windy). Looking back on mapmyrun, even I think I ran even the windy sections close to 5.00 pace.
