Walk 100k in May is a challenge to walk 100km throughout the month of May whilst raising money for Macmillan's services to support people living with, or affected by, cancer in Yorkshire.

Whether its walking through historic Yorkshire towns, walking your dog along the coast, or going for a stroll with friends or family through the beautiful Yorkshire countryside, every step you take will take you closer to your fundraising target.

Plus every Friday during the event, one lucky walker will win a pair of tickets to York Raceday as part of Macmillan's partnership with York Racecourse.

Whatever your reason, whoever you do it for – kilometre by kilometre you are helping Macmillan support even more people living with cancer, who need your support now more than ever. Find out how your Walk 100k in May donations could help on the how it helps page.

Yes! There is no cost to register, we just ask that you aim high and raise as much as you possibly can for people living with cancer.

Yes, absolutely. Show us what you’re made of! Sign up here.

Please register here and you will be taken through the process to set up your profile and fundraising page on the Walk 100k in May website. You can also create a team page if you are taking part with others.

Please note we are unable to link any other online giving pages (including Facebook donations) to your profile.

First you will need to register to participate in the challenge. Once you have set up your profile and fundraising page, you will be able to share your unique page URL with your friends and family where they can make a donation through our secure payment gateway using a valid debit or credit card, Google Pay, or PayPal.

We advise you not to use Facebook ‘Add a Donate Button' or create a ‘Facebook Fundraiser’ for your challenge, as this will process the donation through Facebook and it will not appear on your Walk 100k in May fundraising page. Sorry we are not able to add these donations to your fundraising page.

Getting your friends and family to support and sponsor your challenge is a good excuse to bring people together and it’s all for a good cause.

Here are a few tips to help:

• Spread the word! The more people you tell, the more sponsors you’ll get, ask friends and family to give as much as they like, no matter how big or small, anything they can give will make a big difference for people living with cancer.
• Post on your socials: Share our free social media images with a link to your fundraising page on your channels. Let your followers know how you are preparing and share your reasons for taking part.

Gift Aid is a great opportunity to make your voluntary donations to Macmillan worth 25% more – without spending an extra penny. It enables charities like us to claim the basic tax that donors have paid on their donations back from HM Revenue & Customs. If every supporter agreed to Gift Aid, it would raise hundreds of thousands of pounds more to support people living with cancer.

To be eligible to add Gift Aid to your donation you must be a UK tax payer and you must have paid or will pay an amount of Income Tax and/or Capital Gains Tax for the current tax year (6 April to 5 April) that is at least equal to the amount of tax that all the charities and Community Amateur Sports Clubs (CASCs) that you donate to will reclaim on my gifts for the current tax year. Other taxes such as VAT and Council Tax do not qualify. The charity will reclaim 25p of tax on every £1 that you have given. Make sure you enter the address where you are registered to pay tax; usually your home address.

If you choose to donate to a Walk 100k in May fundraiser on Facebook, please note that this amount won’t appear on the fundraising page, but your donation will still go to Macmillan Cancer Support.

First thing to do in this instance is check your Junk Email folder. Sadly the amount of spam going around the internet means that Junk Mail filters are becoming more and more complex. It is difficult for us to be 100% sure that your donation receipt will be delivered to your inbox successfully. If the receipt is not in your Junk folder and you still haven't received it after a couple of hours please contact us at macmillanevents@macmillan.org.uk.
