Rower Katherine Grainger is back in training

Olympic champion Katherine Grainger is to return to training and has an eye on the Rio Games in 2016.

The former Bearsden Academy student has not trained competitively for the last two years .

The Scot won gold in the London Games two years ago with partner Anna Watkins , and will be 40 when the Rio Games take place.

Grainger told BBC Sport recently that it had been an ‘agonising decision’ and there were ‘big challenges ahead’.

She added: “If I don’t try, I’ll always wonder ‘what if?’ and for me, that will be so much harder to live with.”

Former partner Watkins expressed her delight at the news, but confirmed she is “unlikely” to join Grainger because she is pregnant with her second child.

As well as the gold in London in the double sculls, Grainger’s other honour includes: three Olympic silver in the previous three games; Sydney 2000 in the quad sculls, Athens 2004 (coxless pair) and Beijing 2008 (quad sculls).

She was also world champion in double sculls in 2010 and 2011; quad sculls 2005, 2006 and 2007 and coxless pair 2003.
