Registration FAQs

The challenge is to walk 100 miles in the month of May, but you can do 100 miles any way you choose. Walking. Rolling. Running. In the wild, the city or on a treadmill. 3 miles every day or split another way. It’s entirely up to you!

Free! There is no participation fee for this challenge.

The challenge officially starts on 1 May 2026, but we're more than happy for people to adjust the dates of the challenge to suit them. For example, some people may start earlier because they’re unable to take part for the whole of May.

The challenge is open to everyone.

People aged 16 and below can get involved, but they will need to have an adult register them on their behalf.

There is no minimum amount that you must raise. We just ask you do your best to collect as many donations as you can to support those affected by breast cancer.

To sign-up for the challenge and receive your free Breast Cancer Now T-shirt, you’ll need to complete our registration form and set up your fundraising page.

Unfortunately, you will not be able to combine your fundraising totals across Facebook and JustGiving, as they are two separate fundraising platforms.

However, there’s no need to worry as all donations from both platforms will still come to us automatically.

If you have someone wanting to donate who doesn’t have Facebook, then we suggest collecting the money directly and donating to your own fundraiser on their behalf. Just remember that if you do this, you will not be able to claim Gift Aid on this donation, so make sure to leave that box unticked. 

If you or anyone else with a Facebook account is having trouble donating to your fundraiser, please get in touch with the Facebook help centre, who will be able to support.

If you or anyone else is having trouble donating to your JustGiving fundraiser, please get in touch with the JustGiving help centre, who will be best suited to help.

If your Instagram fundraiser is connected to our main Facebook fundraising campaign, then yes, we’ll be able to see in our internal records that you're fundraising via Instagram, along with the amount you've raised and a list of donors.

However, we won’t be able to view your actual Instagram fundraising page or any of the posts associated with it, as Instagram doesn’t currently allow access to that content directly.

If you or others are having trouble donating to your Instagram fundraiser, the best place to find help is the Instagram Help centre.

For issues specifically related to charity fundraisers and donations, take a look at these pages:

This could be pound for pound, or a contribution up to a certain amount. Either way, we’d be more than happy to provide a letter of authority to support your request. Just pop us an email at virtualchallenges@breastcancernow.org.

For more information, take a look at our Matched Giving guide.

Once you have set up your fundraiser, make sure to share it on your social media channels with your friends, family, and colleagues!

Download our Walk 100 Miles in May distance tracker, to keep track of your miles throughout the month!

Alternatively, feel free to keep count of your miles using your own fitness tracking app.

This challenge is built on trust so we won’t be asking you to prove that you’ve completed your 100 miles. We just ask that everyone taking part does their best to achieve as many miles as they can.

We suggest sharing photos and videos of your walks on your fundraising page and in the Facebook group - we’d love to see them!

Please email virtualchallenges@breastcancernow.org to let the team know.

Although the goal is to walk 100 miles throughout May, we understand that it’s not feasible for everyone. This is a personal challenge and so if you need to change the distance or timescale of your challenge, that’s completely fine. 

Choose a distance that is a challenge for yourself, and we will be there to support you the whole way through! Your health and safety are the most important thing to us, so don’t push yourself too hard.
