The regional championships are held over a couple of meetings and are incorporated into the Welsh Athletics Junior Open Series.
Dingley took gold in the under-17 boys’ 60m hurdles event with a 8.53 second run, which was just 0.01 of a second slower than the PB he had set the previous week on his way to reaching the England Age Group Championship final.
Meanwhile, a number of Armada athletes will be in action at the UK Athletics Indoor Championships in Birmingham this weekend.
David King is the current 60m hurdles champion and he will be looking to retain that title by edging out his GB Olympic team-mate and the 2018 world indoor champion Andy Pozzi on Sunday.
The day before, Erme Valley Harriers athletes Will Battershill, Nathan Brown and Sam Trigg-Petrovic will be in action, along with City of Plymouth’s Tyler Johnson.
Steeplechase specialist Battershill will compete in the 3,000m flat, while his team-mate Brown will compete in the 800m and Trigg-Petrovic will take part in the triple jump. Johnson, meanwhile, will be in action in the 400m.
Brown goes into the championship having smashed his 800m PB this month, clocking 1:52.62 at the Indoor Inter Varsity at Lee Valley.
