KATHERINE Grainger has confirmed she will row at the 2012 Olympic Games in London.

The 33-year-old Marlow rower has three Olympic silvers and thought long and hard about committing to another Games after returning from Beijing.

But the most decorated female rower in British history is going for gold again.

She said: “I’m not going to experience the Olympics.

“It’s about getting the best result.

“I’ve have been incredibly lucky to be in fantastic boats at the last three Olympics and get fantastic results. I knew I could only do it again, realistically, if I was at the peak of my abilities.

“It’s not a decision I’ve taken lightly. One of the people I talked to was the head doctor and physio to see if physically it was possible.

“Everyone’s come back very positive, and the level I need to be at is very achievable.”
