Swim Watch

Went swimming this morning, first time in a while.  Strange thing happened, did 72 lengths, 1800m, but then later on, even though saved, it dropped by a length!

After a bit of investigation, it seemed that I stopped my session and then pressed go again, while I was having a fun swim with the kids.  Just a coincidence that the distance came out about the same!  Also, funny that the calories used was higher on the fun swim than the length swimming!

Well apologies if I've sent you to sleep with that story, if you read all that!
