The third post in a video blog series as Olympic medallist Katharine Merry shares her journey from elite sprinter to Great North Run pacer

Sydney 2000 Olympic 400m medallist Katharine Merry continues her training to be a Duracell bunny pacer at the Simplyhealth Great North Run on September 10.

Taking inspiration from the IAAF World Championships in London and the athletes on show, Katharine continues to go further for longer, and runs the furthest she has run so far: 8.3 miles.

With less than a month to go until the half-marathon, Katharine will be upping her training to hit her targets.

Part one in her vlog series can be found here, while part two is here.
