Visitor Information: Running Mania 10K Event

On Sunday 11 October, Running Mania will be holding a sold-out 10K Run. The Gardens will be open as usual from 10am, although we recommend visiting from 11am onwards to avoid the temporary road closure on the eastern section of Jermyns Lane. Due to ongoing building works the electric vehicle charging bays and some accessible parking spaces will be unavailable from 21 Sept - 16 October. More information
