Road closures
The Big Half returns on Sunday 7 September 2025
To ensure the safety of participants and spectators, road closures, parking suspensions and footpath closures will be in operation.
In the lead-up to the event, you will spot yellow road closure signs displayed on affected roads. On Event Day, police officers and stewards will help answer your queries and to ensure a safe and secure event.
Thank you for helping to make The Big Half a fantastic event for our participants and the local community while raising thousands of pounds for charity.
