2. An intermittent beeping sound coming from the back of my swimming hat - this was reassuring on three counts
A. It proved that the Garmin was still there B. It proved that it was still functioning and C. It proved that I must have pressed the correct button as I concluded (after wondering what the f*#k was all the beeping about) that the autopause function was kicking in, which was borne out by the beep when I stopped to adjust my goggles and the second beep when I resumed swimming - although there were more virtual stops than real ones. 3. 1,232 yards in 20:50 = 29:46 minute miles. The best track of my swim is below.
4. While the surface was a bit choppy and my head bobbed about a bit the elevation profile suggests a very undulating course.
I conducted the above experiment at lunchtime today in Inniscarra Lake with Connie and Pete (The Jedward of triathlon - so enthusiastic) although they were more observers than participants. Connie was very supportive though saying - "I don't mind, it's your Garmin". In case you thought i'd lost it completly I was following in the footsteps of others. .
