Competing at St Sampson’s High, the two-time Commonwealth Games man led out teenage breaststroke star Charlie-Joe Hallett and sprint specialist Jonny Beck to win the concluding event in 50.68sec.
While outside his grand personal best of 48.84 from three years ago, Munro’s recent performance marked a hefty improvement on his 52.13 gala mark from 2013.
It follows a quieter season where he has prioritised his academics and graduation from the University of Bath.
Barracudas coach Sara Parfit confirmed that despite Munro’s intention to work full-time in the UK, he will be available and certainly ‘in the running’ for future Island and Commonwealth Games.
There was also an impressive breaststroke double from the Hallett brothers.
