Swimming tonight was pretty good. I did 1.5 km in total. I wanted to do 2 km, but I missed the bus, and the schedule worked out so that I couldn't fit more swimming time in.
At 6:00 I was 7.2 (130) and had dinner, 30g, which I bolused fully for. At 7:00 I turned my pump off for an hour because I wanted to swim and still had about 2.5u of insulin on board. Then I missed the bus, so swimming got delayed.
At 7:50 I was 7.9 (142). At 8:25, right before swimming, I was 9.8 (176). I swam for 1 km which took me 34 minutes (I timed this time) including some rest stops. Then I tested and was 9.1 (164) at 9:15. I swam for another half km which took 18 minutes. After that at 9:45 I was 7.0 (126).
I got changed and stopped to pick up groceries and such on the way home. A while after I got home, at 10:45, I tested at 14.5 (261) and did a correction.
Still trying to figure out the BG stuff, but at least I went tonight on a Friday evening when I got home later than I thought and then missed the bus—and it was raining! Lots of reasons to not go, but I did.
