4.3Did 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.

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.

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

Hilly at times but the descents made up for it.

Is your question about booking your place?
I have just entered this race via let’s do this and haven’t received a confirmation email. No response to emails to customer services either. Can you help?
Hi Hannah, Rachel's sent that over to you so you should have the info now :)
Will the results go on power of 10?
Is this event still going ahead at this time (30/10/20) I appreciate things are changing all the time.
they have put up the signs announcing the road closures, so now will see if there is anything in a potential lockdown that might change things
Hi is this definitely not being cancelled?
Hey Peter! At the moment this race is still going ahead. RunThrough (the organiser) have been doing a bunch of other races during this period and they've all been COVID secure and felt really safe with proper social distancing etc so am definitely expecting and looking forward to this going ahead. If anything changes then RunThrough and Let's Do This will email you. Hope you have a great race!

What will be provided at the Aid Stations?
Are headphones allowed?
Hi there. Thanks for getting in touch. Headphones are allowed but the event organiser strongly advises against using them due to the nature of the event.
Can we wear head phones/head phone at this event please?
Hi there, we’d strongly advise against it – the nature of the events means that you need to be aware of your surroundings and be able to hear marshals instructions
can you let me know how hilly the event is please
