Legs are still sore from Monday's leg workout. Was going to take another day off from running, but after walking a lap around the track the legs felt like they wanted to run. I decided to try some interval work. One lap at a fast 6-7 minute/mile pace and one lap walking. Did that for about a total of 2 miles.
It's been a long long time since I've done any interval work (probably since my high school track days) but it felt good to stretch the legs out and run fast, even thought I can't keep it up for very long.
