hot tubs and the like as swim training ...

Ryan says: "for some reason I don't think spending 15 minutes in a hot tub per day on vacation counts as swim training."

I beg to differ. When Jack, pictured below, was "training" for the 4-yr-old triathlon, one day after bath time I was getting his brother dressed while Jack was still playing in the bath and I heard what sounded like water splashing ALL OVER the bathroom, so I went in and, wouldn't ya know it, water WAS splashing ALL OVER the bathroom as Jack was in the bath flailing with a combination of forward crawl and butterfly. He got a "Jack, what are you doing!?!" He said "twaining for my twi-a-tha-wahn, daddy"
