Seven year old Noah, his dad Ryan and cousin Lucas plan to walk 15 miles from Rawcliffe to Hook and back via Rawcliffe Bridge, Old Goole, Goole, and Airmyn to raise funds for Lindsey Lodge.
Noah said: "Lindsey Lodge have helped and supported my grandad Andy during his cancer treatment and continues to help during this rehabilitation period. Grandad is back in the Hospice now to help him get back on his feet as he continues to fight against this horrible disease. Me, my dad and cousin Lucas are going to push our limit and walk further than we have ever walked before to give something back to the Hospice."
The walk is taking place on 28 June, which is Noah's Grandad's birthday.
