With elder brother and 2019 silver-medallist Cam absent, following injury disruption and concerns over self-isolation, 20-year-old Ala’s sole local company at Manchester National Arena comes from championship debutant Peter Curtis.
Curtis has made impressive strides in recent months over their shared 400m hurdles focus – though it is clear who takes the local favourite’s tag.
The younger Chalmers brother last year won the English Championships, in his maiden step up to the more prestigious British equivalent, placing fourth overall just outside a podium of sub-50sec. finishers.
Having now twice broken that daunting barrier at Footes Lane without real competition, he has a very realistic desire to go at least one better in this exciting season finale.
‘What better way to end [the season] than the British Champs with everyone?’ said Chalmers.
‘More than ever, I’m just happy to run against other really good athletes around the country, and it’s lining up to be a good one.
‘I feel I’m in really good shape and last time I was at this track, I took home first place.
‘Just for myself, if a medal happens, I will be happy no matter what.
‘A lot has changed since last year and I feel I’m in better shape and a better place both mentally and physically, so I’m determined to have a good, smooth race and see what happens really.
‘Hopefully both me and Pete can both run personal bests and do our best.’
The 400m hurdles get under way with tomorrow’s heats from 6.50pm ahead of a Saturday 1.25pm final.
