We ask each Muddy Dog Trek participant to fundraise £150 (for the 10k distance) or £200 (for the 20k distance) to help us to be here for every cat and dog.

The easiest way to fundraise is to set up an online giving page and share it with your friends, family and colleagues.

If you and all of our Muddy Dog Trek 2020 participants raise £200, this would pay for the care of 80 dogs for the duration of their stay here at Battersea.


Both routes start and finish at Firle Place, a beautiful country estate in the South Downs National Park.

Can any dog participate?

The Muddy Dog Trek is a challenging event and will not be suitable for all dogs. Please consider the below before registering.

All dogs must be at least one year old on the day of the event, be sociable with other dogs and humans, they must be fully vaccinated and they must not be in season.

Many flat-nose, overweight or older dogs might struggle to complete the 20km distance but may be able to complete the 10km distance if they are used to regular long walks. We advise speaking to your vet before registering as all dogs are different. We also advise that in the lead up to the event, you should consider going on a few long walks, gradually increasing the distance to improve your dog’s stamina prior to the event.
