The "washing machine" effect for the swim sustained for the whole of the initial 225 m leg, and still had some body contacts into the 2nd lap. Felt tired and lost the pack on the final lap.

The best swim split I've done in terms of percentile (30%).

No

Nearly forgot to remove my cap and reminded by official

Got cramp in both legs at the start of the run which seriously affected my first km

This was the 3rd time I did the race at the same location, previously in 2016 and 2017. However at that time I was new to the sport and didn't want to run more than 5 km so I did the short course (swim 500 m, run 4 km) instead. I did my first 10 km running race late 2017 since then I did the long course in local aquathons every time.

In terms of percentile, this was by best race in both overall ranking and swim split, but my run split (52%) was much worse than when I was a beginner in 2016 (38%). My running speed was slower than back in 2016 as well, although my swim speed was improved REALLY a lot (I performed at about 33.5 minutes for 1.5 km OWS races earlier this year)
