6x400 @ 5-k pace

Today was an expected easy workout, but I changed it up a bit to make it harder. I was supposed to run 6 400 meter or 1/4 mile intervals @ a 5-k pace. For me, that pace would prob be around 7 minutes. Instead of running at a 7 minute pace, I ran at a 6 minute pace. It seems like a small difference in numbers, but in running, 1 minute is huge. Overall it was a good workout. My left shin got tense at the end but things felt good. Afterwards, I did a heavy stretch, which always feels great.
