Event overview
The Kent Downs 50 Ultra Challenge has a basecamp near Maidstone, with parking and weekend camping options.
The main 50km loop 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.
Along the Len Valley Walk to the majestic Leeds Castle, then the North Downs Way back to the showground finish line and celebration. It’s easily accessible; you’ll get full support and with 25km and 10km options also available - there’s a Kent Downs Ultra Challenge® waiting for you!
The Ultra Challenge Experience
This challenge is part of the UK's number one series of trek and trails runs for a wide range of ages, fitness and experience levels.
Choose your challenge and do it at your pace. The level of support enables you to go further, whilst enjoying the great outdoors, camaraderie, and the challenge. There are marquee rest stops, lots of food and drink, medical and massage teams, with a fully signed route to guide you.
A big finish-line celebration awaits with an amazing sense of achievement and once the aches subside you’ll feel energised, up for more of life’s real challenges – and, maybe, personal horizons redefined.
This event is part of Kent Downs 50 Ultra Challenge.
