The Kent Downs 50 Challenge is a NEW end of season Ultra Challenge – in the ‘Garden of England’ – with a basecamp near Maidstone, parking & weekend camping options.

The main 50km looped route heads anticlockwise around the Kent Downs – starting on the North Downs Way to Blue Bell Hill, around picturesque Aylesford, and following the River Medway to Mote Park at halfway for a picnic.

All levels of experience are welcome - you can walk, run or jog!
