1st December 2025 - 31st December 2026 Find your local run
We have partnered with Run For Charity to help you find the perfect challenge. With events across the UK and throughout the year, there’s always a challenge for you.

The Kent Downs 50 Challenge is a new end of season Ultra Challenge in the ‘Garden of England’, with a basecamp near Maidstone. Choose to walk, jog or run the full 50km or one of the 25km or 10km routes to support families affected by dementia.
The main 50km looped route heads anticlockwise around the Kent Downs, starting on the North Downs Way to Blue Bell Hill and around picturesque Aylesford. You’ll follow the River Medway to Mote Park for a picnic at the halfway point before heading along the Len Valley Walk to the majestic Leeds Castle. The North Downs Way then circles back to the showground finish line and celebration. Choose to take part in one of the following distances:
Your entry includes free food and drink at regular rest stops, plus support including medics, marshals and massage. As you cross the finish line, you’ll receive a glass of fizz, finisher’s t-shirt, and a medal to commemorate your achievement, before heading to a BBQ and a well earned rest.
