You can add an official event t-shirt to your entry at checkout for more than 30% off. Produced in partnership with RT Kit, it features the event logo on the chest and is the perfect keepsake to celebrate your race. Offering the t-shirt as an optional extra helps us keep entry costs lower for runners who prefer not to include merchandise.

Event Information
During the race:
We will have marshals all around the course as well as KM signs and arrows. Please be aware that there will be spectators and members of the public using the park – be aware of people walking, dogs & bikes.
Other things to note:
There WILL be pedestrians, please be aware of people, dogs & cyclists. We have marshals around the course and signs but this is not a road race, you have to pay very close attention to where you are going. We do not recommend you use earphones and you need to pay close attention to everything around you. The race takes place in a busy public common and we can have no control over stray dogs or people running the opposite direction etc so please be aware of your surroundings.
Please email info@runthrough.co.uk with any questions.
