The start line is positioned at historical Knebworth House for a dramatic effect, and the half marathon route explores the beautiful gardens of Knebworth Park before leading runners out to the surrounding countryside. The Hertfordshire Half Marathon is a Road closed event which gives runners a rare opportunity to have the roads for themselves, this is unprecedented in this neighbourhood.  So, get out there and enjoy it.
