About the London Halloween Charity Walk

Why not treat yourself to a hair-raising hike around some of the capital’s scary streets and historic haunts? Gather your bravest guys and ghouls to make up a team – or go it alone if you dare and meet up with other chilling challengers.

London Halloween Charity Walk Route

The event starts and ends at the Oval, where our creepy dungeon keepers will meet, greet and shock!
Once you escape there are ghostly looped routes to follow, with zombie rest stops along the way. And if you manage to get back in one piece, a macabre medal, a glass of fizz and hot food and drink await you – plus a souvenir bobble hat to ward off the chills as you head off home.

Why take on this challenge with Dementia UK

Head to the Dementia UK Ultra Challenge page to find out full details of prices and to sign up.

  • 25km Challenge
  • 10km Challenge

Full sponsorship – you pay a small registration fee and we’ll cover the remaining cost of your event place as long as you hit your fundraising goal! As we are an official charity partner, you will receive a 50% discount on the standard registration fee below.

  • 25k registration fee £20, fundraising target £249

Mixed funding – pay half the cost of your event place yourself, fundraise a bit less and we’ll cover the balance of your place in the event.

  • 25k registration fee £50, fundraising target £150

Own Place Fundraising – you pay the full cost of your event place yourself, then fundraise as much as you can – there’s no set target or deadline, and no cost at all to Dementia UK.

  • 25k registration fee £89, no minimum fundraising target.

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.

Enthuse

Setting up an Enthuse 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 Enthuse 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 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.

The Ultra Challenge website has full details of the event. You can get in touch with the Ultra Challenge team for specific event questions at: info@actionchallenge.com

How to pay in your fundraising

The easiest way to send cash donations to Dementia UK is by donating to your online fundraising page. Alternatively, you can:

• donate via our website

• send in a cheque made payable to Dementia UK. Enclose a note including your full name, the email address that you used to register for your tote bag, and an explanation that you raised the money for the November Knitting Challenge. Post it to us at:

Dementia UK, 7th Floor, One Aldgate, London, EC3N 1RE

• make a bank transfer: please email virtualevents@dementiauk.org for our bank details

How your money will be used

Every penny you raise will make a huge difference to families facing dementia. Each donation, no matter how big or small, will help you reach your target. Did you know that someone simply donating £4 to your fundraiser could pay for the telephone costs of one family calling our free Helpline for immediate support.

See the impact that your fundraiser could make:

  • £ 250

    could fund a new Admiral Nurse

    to run a full day of face-to-face appointments for families affected by young onset dementia (where symptoms develop under the age of 65).

  • £ 557

    could pay for two Admiral Nurses

    to answer calls on our Helpline on a Sunday, when other dementia services are closed.

  • £ 1 ,250

    could fund a new Admiral Nurse

    for a whole week to support a community where people are struggling to access local dementia services.

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.
