Video: Katherine Grainger unsure over retirement plans

Olympic gold medallist rower Katherine Grainger has admitted that she is yet to make a decision regarding her future.

The 37-year-old, who won her first gold medal at the London 2012 Olympic Games last summer, has insisted that she will try not to let her heart rule her head when considering whether to compete at Rio 2016.

While the Glasgow-born athlete, who nabbed silver medals in the three Games previous to London, has admitted that she still gets the buzz of working within a team, she has stated that she won't make any rash decisions regarding her career.
