Yesterday, after I dropped the kids off at school, I went to Jessica's to meet her for a long walk. From her house, a lollipop route around the state park is exactly seven miles, so we chose to do that route. It took us about an hour and forty-five minutes, and my legs felt fatigued but good at the end. Then I woke up this morning, and I was SO sore!
I never get sore from running (unless I do a crazy tough workout, then I might have a little soreness the next day); but switching things up yesterday by doing a long walk used some different muscles and I definitely feel it. It's a good thing! We already made plans to do it again next week.
