I took my six year old out in the stroller for a slow 3 miles. He is getting so big!! He does a great job riding along though. He took his soccer ball so he could play on the football field while I did some speed work around the track after the 3 miler. He was kicking it through the field goal posts, which we both thought was pretty awesome. I played with him for a bit before walking home at sunset. It was a pretty awesome workout overall!
