PBed every. Single. Discipline.
01:20:26 with a gyppy knee, wind, roadworks and a sub-optimal meal the night before. 00:04:11 and 5.2% overall faster than my fastest TTT, 2.2% faster than my fastest swim, 2.4% faster than my fastest bike, 1.2% faster than my fastest run. An overall improvement of 00:14:36 (18.2%) on my first one, 00:08:46 in the swim (28.2%), 00:08:46 in the bike (20.6%), 00:03:03 (10.6%) in the run.
You can clearly see where the HRM didn't work at the start of the swim (always happens); T1 (the dip shortly after 15 minutes); the non-compete zone (the gap between the end of the bike course and T2) and T2 (around the 52 minute mark) and the fact that I took it relatively easy in the run (my heart rate was -lower- than during the cycle) and turned up the heat twice (once around 1hr 7, and again at 1hr 17ish), then a sprint finish (the tiny squeak of a peak near the end) before forgetting to stop my watch for a little bit after the finish.
Very very pleased.
