The two-time Olympic gold medalist quits after over ten years in the sport.

"It's nothing to do with age really, it's just about situation for me and personal preference.

"Before Rio I knew that this was going to be my last one, I'm definitely not going to go on for another four years after this.

"For me it's just taking it's toll on my body, and I'm tired of it. I'm satisfied that I've done my job and done what I set out to do really."
