This October, Mind in the City, Hackney and Waltham Forest is celebrting 40 years of providing life-saving mental health services

To mark the occasion we have launched the 40for40 challenge. All you need to do to take part is dream up an activity based around the numbers 40 or 4 and 10 that suits your ability and complete it during October

It could be something as simple as running or cycling 4 miles every day for 10 days, holding a bake sale and selling 40 cakes or even 40 push ups. There are no rules - just choose your own challenge and get stuck in!
