4.25 mile interval run

Went to the gym with Shari today. She did elliptical while I ran on the treadmill. I got in a 4.25 mile interval run. My intervals were .5 miles of running at 9 mph and .25 mile recovery. It was a good run but I should have gotten outside. I didn't even realize how nice it was going to be outside today until it was too late....
