Nice place. Good organization and logistics. I enjoy the run.

The run itself was great. A lovely scenic and smooth course I ran my quickest 10k for a few years. However I was a bit frustrated to arrive at 9am for the 9:30 am start to find I could drive into the estate because the half marathon route meant the roads were closed. It meant a long walk in to the event village. Hundreds of people had a similar problem. If the instructions said I needed to arrive by say 8:45 to be able drive in then I would have.

Hilly. This one is in the grounds of Knebworth, you will be finishing outside the castle. The route is a little hilly, you will be running in and out of the grounds. Aim to be there earlier than a normal race due to the single track car entrance. There is car parking on site, which is a field of long grass. The goodie bag had to be THE best of all my half marathons, it included a large bag of bath salts, excellent! Crowd support is really only at the end.
