I would like to wish Aaron the very best of luck with his attempt at The Great Walk on behalf of the Cystic Fibrosis Trust. What a diamond geezer for attempting such an heroic challenge - I hope everything goes extremely well for him. Do your best Aaron – you know it makes sense!

Good luck with your challenge. What an epic journey I hope it all goes well. Unfortunately owing to all my commitments including charity work I will be unable to get involved with the walk.

I hope it all goes well and you raise lots of money for the Cystic Fibrosis Trust.

Good luck Aaron with this tremendous challenge - truly an ultimate test!

What an amazing challenge Aaron! As you know I'm checking my dates because I’m hoping to join you on a leg of the trek.

I wish you the best of luck, Aaron, in this truly tremendous charity walk. I hope you manage to raise lots of money and get all the support you deserve.

This is a fantastic concept matched by a fantastic man. I have been fortunate to have worked with Aaron and known him when he was unfit and overweight. He is and always will be a role model for anyone who wants to make a difference

I wish Aaron the best of luck with the walk - it will be a great success

All the very best Aaron on your great walk from Lands End to John O'Groats and back and I look forward to seeing you at this year's London marathon.
