Olympic head coach at UK Athletics, Christian Malcolm, said, "Every athlete and their support network should be incredibly proud of their achievement during a challenging last 18 months.
"As we saw from the high-quality British Athletics Championships and trials at the weekend, a number of athletes stepped up and delivered exceptional performances to earn their nomination to Team GB.
"To represent your country at an Olympic Games is an incredibly rewarding achievement, whether you have competed at a Games previously or if this is your first call-up.
"My message to those athletes nominated is enjoy this moment and keep your focus in these last few weeks as we countdown to the Games."
