    Did the Half Marathon in 2019

    I have just ran this half marathon for the first time and I loved it. I would highly recommend this run. It was hilly but as much as you went up you went down. The hill at the end was a challenge but a PB is still possible as I got an 8 minute one :-). Very well organised, great atmosphere, good for spectators. The only downer I can put on this event is the parking, lots of cars getting stuck in the mud including mine and very slow getting out.
  • Did the Half Marathon in 2019

    Knebworth House is a stunning setting for the race. On arrival the race village was busy for the warm-up session. The course took us on a couple laps of the estate before heading out to surrounding country lanes. It was a challenging course with plenty of hills, so hard to run a PB, but don’t let that put you off, a good turn out and supportive marshals and crowds made for a great event.
  • Did the Half Marathon in 2018

    Arrival was plain sailing, although leaving was busy. Men's urinals would be useful too, to reduce general toilet queueing. Challenging & rewarding course. Brutal final 1km, even if I had checked the gradient profiling. Good atmosphere, very scenic countryside, nice medal, awesome goodies for finishing. The 'village' was great, huge bonus of a free massage & enjoyed the music. Definitely a HM worth doing again, pb included! See you next year.

    A bit more information about the gradient and at which miles this applies too.Any toilets on the course.Allowing time to get out of Nebworth as took a long time due to single exit.
  • Did the Half Marathon in 2018

    How hilly it was! Though I still would have done it but I think it should state its undulating in the race description. I did however enjoy the race and managed a Pb, despite the hills!! There were unfortunately more unenthusiastic marshals that let down the enthusiastic ones! When youre running and knackered a boost from a Marshall seriously helps your motivation! Marshall @ mike 11 was great
  • Did the Half Marathon in 2018

    Hilly at times but the descents made up for it.
