Brian and I went out from his house for a 5 mile "easy" run. And while I wouldn't say that I pushed it to an 8K race pace, I was definitely able to push it harder than I've run since the injury and was still able to keep up a short-sentence conversation with him. I screwed up the first half mile of pace, but it would have been around 8:15/mile, I'm guessing. Here are the rest of our splits:
8:13 (into the wind)
8:01 (into the wind)
7:51 (wind at our back)
7:44 (wind at our back)
9:13 (0.58 of a mile, cool-down pace)
The wind wasn't gale-force or anything, but it was definitely noticeable. For the 4 miles where I was actually running fast, our average pace was 7:58 on average.
