Take on the challenge and walk with purpose this summer


Can you tell me more about the event? 

We are challenging you to walk 100km throughout one month this summer. You can choose to join us in June, July or August (or all three, if you’re feeling ambitious!). This is a virtual event, so you can take it on wherever and whenever works best for you. You can do a shorter walk every day or build your kilometres by tackling some longer walks.

How do I sign up for the challenge? 

The first step is to register for your free Dementia UK t-shirt and set up a fundraising page.

Once you have registered and set up your fundraiser, you’ll be ready to go! Get some practice walks in so you’re prepared for your challenge. We can’t wait to cheer you on.

Is there a registration fee?  

Taking part in the Walk 100K Challenge for Dementia UK is free.

Is there a fundraising target?  

There is no fundraising target for this challenge – we just ask you to raise as much as you can for families affected by dementia.

How do I fundraise? 

The easiest way to fundraise is by setting up a JustGiving page. It takes just a few minutes.

Once you have created a fundraising page, be sure to share it with your family and friends via social media, text, email and WhatsApp. We’ll also send you a sponsorship form in the post to collect any offline donations you may receive.

Where do donations to my JustGiving page go?  

All donations made to your fundraiser will be sent directly to Dementia UK by JustGiving. These vital donations will support families facing dementia.

Can I raise money without setting up an online fundraising page? 

You certainly can. We’ll send you a sponsorship form with your t-shirt, but if you need more than one form, simply download and print more copies.

Please ask your sponsors to fill out all the columns so we can claim up to 25% Gift Aid.

How can I send in sponsorship money I collected offline?  

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 t-shirt, and an explanation that you raised the money for the Walk 100K Challenge. Post it to us at:

How do I get my free t-shirt? 

To register for your t-shirt, please complete the registration form here. It will take up to two weeks for your t-shirt to arrive.

I still haven’t received my t-shirt – where is it? 

We’re sorry to hear you haven’t received your t-shirt yet. If you have waited two weeks since completing the registration form, please email and we will investigate.

Can I get more than one t-shirt for the challenge? 

We send out one t-shirt per participant. If you would like to buy more, please visit our shop, where you’ll find adults’ and children’s t-shirts along with additional Dementia UK branded items.

Where and how can I complete my distance?  

You can complete your kilometres wherever you like, however you like! Just make sure you record your walks and keep your sponsors updated on your progress.

How do I record how many kilometres I have walked? 

Strava is a free, easy to use app that can track your kilometres this summer. We highly recommend downloading it for this challenge. You will also receive a challenge tracker with your t-shirt, which you can use to tick off your kilometres.

Can I start early or late? 

Of course! You can do this challenge whenever suits you. The more participants we have, the more families can receive the life-changing support of our specialist dementia nurses.

Can I do more or less than 100K? 

Absolutely. This is your challenge, and you can tailor it to suit you. Just be clear with your supporters about how far you are intending to walk and keep them updated regularly with your progress.

What safety precautions should I take?  

Safety should be your top priority when taking part in the Walk 100K Challenge. You know yourself best and we encourage you to think about the distance you walk at one time.

If you are walking alone, make sure someone you trust knows your plans, always carry a fully charged phone with you, and please do stay alert. We also advise taking rest days whenever you feel you need them, and staying hydrated, especially if the weather is warm.

What if I don’t complete the challenge?  

The only thing that matters is that you challenge yourself and enjoy raising awareness and funds so our dementia specialist Admiral Nurses can support more families. Do as much as you can. Update your sponsors regularly, be clear about how far you’ve come in your challenge, and make sure they are still happy to donate to Dementia UK.
