Just watched your video. Super challenge and incredible cause. Wish you the best of luck from the bottom of my heart mate.

Stuart Potter's amazing "biggest journey" will see him cycling from Edinburgh to London in only 4 days, riding over 100 miles per day, and doing much to raise an awareness of the benefits of exercise in promoting mental wellbeing. He is also well on course to raise a considerable sum for MIND. We recognise that cycling is a fantastic way of getting fit, but this challenge is something else, and I'll be following his progress avidly.

great inspiration! I'm sure it will get people talking about depression which is often misunderstood. Good on you!

this project gives me chills every time I think about it. Thank you for thinking of it and, more importantly, doing it!

I suffered from severe panic attacks when at school. The advice I received? " school can't help you. Go get a job." :0(

Very best wishes!! I'm a bona fide fan of your work!

With my 6,000th tweet, I'd like to urge you all to support a great cause: @biggestjourney. (I don't cycle but I do suffer from depression.)

I'm inspired by you doing this. Good luck and let me know if I can help in any way

Looking forward to following Stuart's @biggestjourney. He finds his peace in cycling, I find mine in singing and performing.

nice to hear about @biggestjourney. Regular cycling & medication are what sort my head out

it's been my absolute pleasure to support u and be part of yr #biggestjourney

I think it's fantastic what you're doing to raise awareness of mental health. Respect, and all that guvnor' *doffs hat*

Can't believe so many people suffer mental illness. Shouldn't be kept quiet - they deserve help without stigma. Good on you

its a charity supporting something that means a lot to us too, happy to support it.

#ff @biggestjourney for being a great inspiration and really working towards eliminating stigma around mental health

Hi, just want to wish you good luck. I suffer from depression and SAD. Cycling this winter has been a great help #Iam1in4

Ur bio is very inspirational !

#Iam1in4 My challenges have deepened my capacity for compassion. I want others to know- you can reach out; you're not alone.

With physical exercise being so hugely beneficial for everyone's mental health it's particularly fitting that Stuart has is testing his body to its limits to raise vital funds for us. Every penny that he raises will help us to continue to provide information and support, as well as campaigning for change to make sure that anyone experiencing a mental health gets the respect they deserve.

what your doing is such a wonderful thing! good luck and i hope everything goes well! :)

#iam1in4 and I'm proud of it. I am the person I am today because of the challenges I have faced-a better, stronger person
