Windsor Half Marathon

Join the team of Battersea runners on Sunday 26 September 2021 and take on this half Marathon in the beautiful Windsor Great Park.

A finish line with a stunning backdrop of Windsor castle is certainly unique and the challenging route makes this one of the UK’s most popular half marathons.

Apply for a charity place

We have a small number of guaranteed places in the 2021 Windsor Half Marathon, so register now to run on behalf of Battersea.

Register now

By running for us you'll be helping lost, abandoned and unwanted dogs and cats find the loving, new homes they need.

The registration fee for one of our places is £25 (payable on confirmation of your place) and we ask that you pledge to raise a minimum of £350.

All the money you raise by taking part in the Windsor Half Marathon, will help us be here for dogs and cats. Last year we helped over 5,000 dogs and cats across our three centres, and tens of thousands more animals all over the country and across the world by training and helping the rescues that look after them.

I already have my own place

If you have already secured your place for the Windsor Half Marathon we would love for you to join our team.

We don't ask you to raise a minimum amount if you've got your own place, but we will support you every step of the way to raise as much as possible.

Why run for Battersea?

As a Battersea runner you will receive:

  • Top quality Battersea running vest
  • Fundraising support from start to finish including materials, ideas and tips
  • Training advice
