A frustrating year on the track ends on a joyful note as the 28-year-old from Perth looks forward to her wedding and a future as Mrs Doyle.

"There's always that extra-special feeling knowing you are going into Olympic year," Child told BBC Scotland.
"It makes all the hard work worth it."
Child's 400m hurdles career has been on the rise since reaching the semi-finals at the London Olympics in 2012, with a second Commonwealth Games silver medal coming her way in Glasgow last year, along with gold at the European Championships.
