World indoor champion Richard Kilty will not defend his 60m title in Portland next month after choosing to focus on the Rio Olympics.
Despite being disqualified for false starting at the British Championships, UK Athletics wanted to select Kilty, 26, alongside winner James Dasaolu.
But Kilty has opted instead to focus on realising his potential outdoors.
“Whilst this has been a really tough decision, looking at the big picture it’s the smart call,” he tweeted.
“This year is all about the Olympics, so going into Portland short of races and taking a gamble that I could run myself into form makes no sense when I could start to focus on my outdoor season early.”
The Gateshead Harrier has an indoor personal best over 60m of 6.49 seconds, but so far has failed to produce similar results outdoors, despite a personal best of 10.05 for the 100m, set at last year’s Birmingham Grand Prix meeting.
“Individually I’m aiming for sub-10 and making the Olympic final in 2016,” the man known as the Teesside Tornado continued.
“As part of the GB 4x100m relay squad, we have a real shot at getting on the podium and are 100% focused on achieving success as a team.”
