After boxing class today, I randomly decided to run on the treadmill, since I was already at the gym... ended up doing a quick 3 miles in 25 minutes. That's a pretty disappointing time considering I used to run 5K's in less time than that. I guess you could call it speedwork. I basically did intervals adjusting the pace from 8:30 down to 6:20 min/miles at the end. It was so hard! I was pretty sore during the run & I'm extremely sore now.
