Time to ease our selection headache?
The discussion of how best to pick a team in athletics has run for many years - alongside other favourites like the false start rule.
When I was an athlete I didn't pay much attention to selection times or the criteria.
My coaches Ron Roddan and Linford Christie always had the national trials in my competition schedule and my remit was to win them and to consistently go under the qualification standard I needed beforehand.
Some athletes are already confirmed in the GB & NI team for next month's World Championships in Berlin.
But many athletes face a sleepless night on 27 July, with the full team announced the following day, taking into account performances at the Aviva London Grand Prix at Crystal Palace which is being televised live on the BBC this Friday and Saturday.
I'm Katharine Merry, former world 400m number one and an Olympic bronze medallist at Sydney 2000. I'm now a mentor to junior athletes as well as working in radio and TV, and as a trackside presenter at major events. I'll be aiming to give you a behind-the-scenes insight to the world of athletics.
