Hertfordshire Runs 2026

  November 1, 2026     Old Knebworth Ln, Knebworth, UK

Training, fundraising for and running a half marathon or 10k for charity is a great achievement. Whether it’s your first run or one of many, ACT will be here every step of the way.

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.
