Kent Downs 50

Take on 10-50km of the South East’s beautiful countryside to help end homelessness

About the event

The Kent Downs Ultra Challenge is a stunning loop through some of the South East’s most picturesque countryside—and a brilliant way to support St Mungo’s.

Starting near Maidstone, the 50km route follows the North Downs Way to Blue Bell Hill, passes through charming Aylesford, and traces the River Medway to Mote Park for a halfway picnic. It continues along the Len Valley Walk to the majestic Leeds Castle before returning to the showground for a celebratory finish.

With 25km and 10km options available, it’s accessible for all abilities. By fundraising for St Mungo’s, you’ll help provide vital services, expert support, and opportunities for people experiencing homelessness to rebuild their lives—making your challenge truly impactful.
