Every penny you raise from your event will help our dementia specialist Admiral Nurses provide a lifeline to more families facing dementia – and we’re here to support you every step of the way. 

Fundraising ideas 

Organising another fundraising activity alongside your main challenge will help you smash your goal. Here are some ideas: 

  • host a quiz 
  • arrange a raffle 
  • hold a sweepstake on how long your challenge will take, or the distance you’ll achieve 
  • organise a bake sale at home, at work or in your community 
  • create a sponsored playlist, where supporters donate to add their choice of song 

Your fundraising welcome pack 

Once you’ve signed up for your challenge, we’ll send you a fundraising welcome pack that’s full of advice on how to meet – and beat – your target.  


Setting up a JustGiving page is a great way to fundraise online. Share your link with family, friends and colleagues, and watch the donations roll in.  

You can use JustGiving to explain why you’re taking on your challenge for Dementia UK, keep track of how much you’ve raised, and even share your training progress using Strava so your supporters can see how well you’re doing. The more you update and share your JustGiving page, the more donations you’ll receive. 

Gift Aid 

If your supporters are UK taxpayers and their donation is voluntary (not proceeds of a sale), we can claim an extra 25p for every £1 donated – at no extra cost to them. Make sure they fill in the Gift Aid form in your fundraising pack or tick the correct boxes if they’re donating online. 

Sending in your donations 

If you’re fundraising through JustGiving, the donations will automatically come to us. If you’ve got cash to pay in, you can do this online, by phone, by bank transfer or by post.

The walk was both emotionally and If I could do something to raise awareness and help other families then I was proud to of completed this challenge in 12 hours. It was a tough walk, but the pain was worth everything and I would do it again just to support more wonderful charities.
