South Coast Challenge Route

Take in some of England’s finest scenery as you walk, jog or run! The event starts in Eastbourne then progresses up Beachy Head, over the magnificent Seven Sisters, and along the famous South Downs Way National Trail with stunning views over the sea. Take a breather at the Brighton mid-point, then encounter Devil’s Dyke: rest stops and several ups and downs all lie ahead before historic Arundel comes into view after an amazing 100km journey.

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 on of the event. For any specific questions about the event, please get in touch with the Ultra Challenge Team 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

• make a payment by phone by calling 0300 365 5500

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’m honest it was the hardest challenge I’ve ever done - mentally and physically. I think I definitely surprised myself but the support from friends and family was amazing.
