Windsor Half Marathon

Windsor Half Marathon has announced the 2020 event will be postponed until next year. The event organisers have confirmed the new date of 26th September 2021 and places are available now. Please see below to apply.

We know how disappointing this will be for our runners and would like to say a big thank you to everyone who has chosen to run for Battersea and raise vital funds for our dogs and cats. We’re incredibly grateful for your support. Battersea relies upon donations to raise the vital funds needed to keep our centres running, and now, more than ever, we need the continued support of the public to ensure we can continue to be here for every dog and cat.

Join thousands of runners in this picturesque half marathon. With the stunning backdrop of Windsor Castle and the autumnal setting of Windsor Great Park, this is one of the UK’s most popular, scenic and challenging events.

All the money you raise by taking part in the Windsor Half Marathon, goes towards the running of Battersea.
