Beat the rain

This was designed to be a long, slow run of 10 miles, but because of the weather it really turned into a near race-pace run. I knew it was going to rain, but just not exactly when. There were dark clouds in the southwestern sky when I got started, but it kind of seemed like the rain might be two or three hours off, so early on I tried to stick to a slower pace.
For a change, I had a headset on and was listening to my book, and when I do that I kind of lose track of my pace. Still, I was around 9:30 for the first three or four miles. After that, it began to look more and more like rain was imminent, so after mile 5 I picked it up a little. As I hit mile 7, a light rain began. I wasn't far enough out yet, but turned around and headed back anyway so I'd be closer to the truck if I got caught in a downpour. By the time I got back to the truck I still had 1.2 miles to go, and it wasn't raining very hard, so I decided to do a final .6 out and back. Just as I finished, the rain picked up, and I wasn't a quarter mile away on my way home when the thunder and lightning came and the sky opened up. It was a perfectly-timed finish.
I ended up with 10.10 miles in 1:32:13 for a 9:08 average. My pace for the last 4.25 miles was about 8:35. For the week I had 26 miles.
Two weeks from today is the half marathon. I'm not confident of it, but I'm starting to think I might be able to break 2 hours.
