This weekend three-time Olympic silver medallist and London 2012 champion Katherine Grainger switched from elite rower, to road runner, taking on the challenge of the London Marathon on behalf of London 2012 legacy charity – International Inspiration (IN).

Having completed the course in an impressive time of 3:55:08, we met Katherine at the finish line and - in between the sweat, tears and elation – spent some time discussing her reasons for running for IN and what the future holds.
