The 29-year-old is ranked number one in the world after achieving her personal best in March earlier this year.
Mickle will take part in the games with good friend gymnast Olivia Vivian, who beat the odds after breaking her back trialling a new move ahead of the World Championship trials in October last year.
Mickle said that while their sports were like ‘chalk and cheese’, it was great motivation having a friend who trained so hard.
‘To win the Commonwealth Games is what this year’s all about,’ Mickle said. ‘If I can become Commonwealth champion and keep my ranking in the top three, people will start to look and be scared.’
Mickle said she could attribute her recent success to smarter training.
‘I have the issue of over training, but now I’ve figured out recovery is crucial in our preparation.’
The gymnast and javelin thrower became friends soon after the London Olympics when they combined to promote Healthway’s Go for 2 & 5 campaign at schools.
