As the Swim England National Summer Meet at Ponds Forge took over from the previous week’s British Summer Championships, Hallett did not take long to deliver senior silver in the 400m individual medley and gold in the 200m breaststroke.
On day one, the Guernsey Swimming Club star completed an impressive breakthrough in the 400m IM.
Having already lowered his personal best by five seconds in qualifying, he then swam a 4min. 37.53sec. final to mark a whole 12-second improvement since his arrival at the prestigious venue.
He had ended the first few lengths mid-pack but consistent swimming thereon, including a masterful breaststroke leg, left him surging towards eventual winner Miles Drabwell near the end.
This compelled proud father Barry Hallett to Tweet: ‘Watching your son receiving a silver medal at English Swimming Nationals with a seven second PB is totally incredible.’
Just the following day, Hallett went one better.
A well-paced performance over 200 breast saw him steal the lead in the swim for home and touch exactly one second clear with a winning time of 2-22.41.
‘Did not think it could get better ... unbelievably incredible,’ added Barry.
. Hallett was also contesting the 50m back and 200m IM.
