Swim day. While the kids had their lessons, I went over to the deep pool and swam some lengths. I had less than a half hour, so I swam pretty hard. I managed 600 before I headed over to the nearly empty hot tub. I haven’t done a hot tub post-swim in a long time. Usually I swim later, and by that time the hot tub is packed. Not only was the hot tub nearly empty, I had the entire swim lane to myself.
