Nine hundred walkers will be joining the Alzheimer’s Society’s Memory Walk around DZG on Saturday morning.
Organisers are urging folk to take part in a 2km stroll or 10km stretch around the site with a chance to see some of the world’s rarest animals en route.
Details are available at memorywalk.org.uk/Dudley where people can sign up or simply register to take part on the day.
The event, which starts at 11am, will be launched by BBC Midlands Today presenter, Mary Rhodes pictured whose mother-in-law has dementia.
