Frequently Asked Questions

Are there water stations?
Yes there will be a refreshment station 5KM into the course as well as at the end of the race.
Is there a bag drop?
Yes. The car park is located next to the start and finish line and we therefore recommend leaving any belongings in your car. There will be an informal baggage drop located within the Event Village. If you wish to use the baggage drop, please collect a baggage label from the information desk and attach it to your bag before handing it in.
Am I allowed to wear headphones?
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.
Are there toilets?
There will be portable toilets within the event village.
Is there a time cut-off?
Yes, there is a strict 3 hour cutoff due to the road closures.
Will there be photographs of the event?
Yes, RunThrough will have an event photographer at the event and photos will be available on their social media pages after the event.

  • Did the Half Marathon in 2019

    Brilliant venue, fab course (that last hill tho!) and a zoo visit to boot. Loved it. Really well organised
  • Did the Half Marathon in 2019

    Brilliant day despite the rain! Well organised on the whole - although more toilets at start could be handy. Loved the finish treats and free entry to the zoo was a bonus! Marshals were very friendly!
