Olympic champion Katherine Grainger has revealed that she is back on the water for the first time in two years with Rio 2016 in her sights.
After three consecutive Olympic silver medals, Grainger finally struck gold at London 2012 as she and Anna Watkins won the double sculls title.
Since that triumph the 38-year-old took two years off from the sport, using the time to complete a PhD in homicide.
And while Watkins has said that she will not defend her Olympic title following the birth of her son, Grainger admits to lure of Brazil is harder to ignore.
"There are going to be big challenges ahead in coming back after two years away,” Grainger told BBC Sport.
"But if I don't try, I'll always wonder 'what if?' and for me, that will be so much harder to live with."
