Participants are challenged to walk 100km with their dog in February to raise funds for Marie Curie, so we can so we can provide more care for people at the end of life, whatever the illness. The challenge officially starts on 1 February.

No, this event is free for anyone to take part. However, any money you can raise for Marie Curie would really help us to reach more people who need our support.

The only thing that matters is that you challenge yourself. However much you achieve, we're so grateful for your support and for raising much needed funds for Marie Curie.

No, you can take part if you're 10 or 110! But, if you're under 16, you will need a parent or guardian to sign you up to the challenge. Please email events@social.mariecurie.org.uk with permission from your parent or guardian.

We aim to get all dog bandanas with you within 10 working days from the moment you order them.

Unfortunately, it appears that Facebook have removed this option. We recommend setting up a JustGiving page instead.

That's great! They can register using this link.

All sponsorship will come directly to Marie Curie. You don't have to worry about this, it happens automatically.

Absolutely! It's your personal challenge and we encourage everyone to adapt it to suit their needs and goals.
