Checkin' My Guts

Today, I did my first speed work of any sort in about a month. I ran the Gut Check workout which is 1 minute hard 1 minute easy, 2 minutes hard, 2 minutes easy, 3 minutes hard and 3 minutes easy. I did it 3 times. I ran the "hard" repeats at 7:00/mile pace, and the "easy" portions @ 10:00/mile pace. I didn't feel like I was gonna die, but I DID feel it. I finished off with some stretching and worked my core. All in all, I was pretty pleased with the workout. I ran about 5 miles total (including my warmup).
