5/6 Med Long Run

This run started at 51 and drizzly, and ended up turning to heavier rain by 4 miles in. :) Drivers seem to get even more stupid in the rain. Good freaking grief.

Good run. Really slowed down after the first 6 miles, though. I have noticed the performance hit at 5-6 miles in some other runs before. The 12 miler 2 weekends ago comes to mind. I wonder if it might be a change of internal fuel of some sort? If it hadn't happened before I'd think it might be that I forgot my GU. And water bottle.

When I crossed the 6.1 marker I realized I was within 10 seconds of the time from yesterday. Yay, consistency! Actually when I drop the splits into Excel I was actually 2 seconds faster than yesterday, at the 6 mile marker anyway.

9.03 miles in 1:39:12 (10:59/mile) @ 141 bpm
1 - 9:49 @ 140 Yay! Sub 10!!!! (Again, a first mile split can't be trusted)
2 - 10:31 @ 141
3 - 10:46 @ 142
4 - 11:16 @ 141
5 - 11:25 @ 143
6 - 10:50 @ 142
7 - 11:21 @ 142
8 - 11:34 @ 142
9 - 11:23 @ 142
0.3 - 10:46 @ 144

Did two blocks of faster running 'off the clock' to get back to the office a little faster. Tired of getting rained on.

I have noticed after the last couple of runs that my core, not my legs are sore. I'm currently thinking that since my speed has gone up, I'm activating different muscle groups.

The Black Hole Mileage Threshold (that magical point at which if I walk by food I just seem to magically absorb it) seems to have moved a little higher since the last training. I'm hitting it now at 50ish miles instead of at 35 or 40 like last time.
