I’ve been swimming a lot while here in Greece. Not so much in the ocean, though I’ve done that too. I’ve been swimming laps in the above 25m pool which is nearest our room and dedicated to exercise and not for playing in. I breastswim in one direction and crawl on the return.
In 2019, I spent a couple of months lap swimming in the early mornings at a nice sports club in Da Nang, Vietnam. Like back then, during this morning’s 1000m swim, I sometimes lost track of my laps and probably added at least an additional 100m to my original goal. Which is perfectly fine. But I think I need to invest in a lap counting watch of some kind.
