The events, being organised by Jane Tomlinson’s Run For All, are set to generate a huge boost for local charities big and small.
The fun gets underway with the half marathon at 9.30am, followed by the children’s runs from 9.50am.

“A certain amount of disruption is inevitable and we would like to apologise in advance for any inconvenience caused. All closures will be lifted as soon as possible.”
