Go conker crazy!

Don't miss the third annual Hampstead Heath Conker Championships. The event will run whatever the weather and it's being played in a knock-out format, with two junior classes and one for adults.

Bring along your own lucky conker or use one of the harvest thoughtfully supplied by the Corporation Of London (a mixture of baked, vinegar soaked and fresh from tree available).

Parliament Hill Staffyard, Off Highgate Road, NW5 (020-7482 7073). Sun 10 Oct, from 2.30pm, free, children must be accompanied. www.cityoflondon.gov.uk
