I produced, filmed and edited this piece for the BBC Sport website in early 2013 at Katarina's home track in Liverpool. Link to BBC Sport website version: www.bbc.co.uk/sport/av/athlet.... Katarina and coach Mike Holmes reflect on her success at the London Olympics 2012 and talk about the progress that needs to be made for her to compete at the top level of heptathlon against world number one Jessica Ennis. K J-T went on to have a great season, finishing 5th in the World Championships in her first year as a senior. Produced, filmed and edited by Ian Bucknell.
