Macmillan Cancer Support

No one should have to face cancer alone.

Macmillan will move mountains to help people with cancer live life as fully as they can. If you’re diagnosed, your worries are shared.

And they don’t stop there. They're going all out to find ever better ways to help people with cancer, helping to bring forward the day when everyone gets life-transforming support from day one.

But without your help they can’t support everyone who needs them.

Team fundraising

If you sign up as a team, you will need to raise the minimum fundraising amount of £250 for each member of your team. You can, however, choose to split the total in any way you like between the team if some people are comfortable raising more than others.

What a great day, inspirational people everywhere, each with their own individual story. Kim and I feel elated and honoured to be among you all. Still aching, and raised money for a cause very close to our hearts. Ian Watts, Peak District Mighty Hiker

A challenge that pushed me both physically and mentally. I'm not sure what aches the most; my legs or my face from smiling so much! Thank you. Kate, Mighty Hiker

The atmosphere was amazing, we saw so many people encouraging each other and it felt so wholesome. Can’t wait to do my next Mighty Hike. Anastasia, Jurassic Coast Mighty HIker
