I understand this wet-suit assisted speed does not translate to equivalent in-pool speed, but still, I'm very pleased. Thanks greatly Salvo for this valuable breathing tip, and to likewise to all others for your support and kind help.
P.S. I have just been able to fix a corrupted Garmin Connect file, and I find that my swim time as I recorded it was actually 47:41 (or less!). The previous number was the official time as recorded by a chip reader I passed once I climbed up some way up on the beach. This makes for a minor improvement of 2:30/100m average pace.
Congratulations on your tri swim--nice to be able to swim relaxed and at a good pace, with all the distractions of a race going on around you.
