During the warm-up, having their swimmers do some sprints Is it obligatory to bite one's tongue when being a swim coach, maybe ? Ah no. Works fine without tongue between lips, but then you need TWO stop watches! "Hmmm, well, not bad, but next time you better..." "Aaaaaand, go!" All these were taken during the warming up sessions on either Saturday, 28 June, or Sunday, 29 June.
