The theme for this year’s challenge is 7 in 7: Together.
“Bringing the MND community together has been fantastic for us. For those families to share in these moments, when you have spent so much time alone, is great, Sinfield said.
“That’s why it’s 7 in 7: Together.”
He praised the “immense” support he had received since his fundraising journey began.
As part of this year’s challenge, members of the MND community will be invited to join him for one mile each day.
“To see the support, the awareness, to see the fight and inspiration that we have taken – but also the MND community has taken from it – has been brilliant.
“Without the support, I don’t think this is possible.”
