Anna and Martyn Barrow met him on the final day of his 7 in 7 Grand Finale challenge on Saturday 3 October.
Anna was diagnosed with MND three years ago and Martyn is now her full-time carer.
The couple wrote a letter to Sir Kevin, also signed by their three daughters, Tilly, Eve and Fallon, describing what his support has meant to them.
They wrote “Our words can never be enough to express our gratitude for what you have done for our family and the entire Motor Neurone Disease community.”
The family have taken part in his challenges by banging a drum at stops in Manchester and Sheffield.
In their letter, they said “You haven’t just raised vital funds and extraordinary awareness; you have wrapped an entire community in love and made us feel seen, heard, and never forgotten.”
They added “When the road feels impossibly heavy, seeing your determination gives us the courage to keep going.”
