A team of three will be cycling more than 400 miles to raise cash to help pay for an operation to help a young boy walk.
The sponsored cycle ride is in aid of six-year-old Cameron Harper from Castleford who has cerebral palsy.
Cameron needs an operation that will help him to walk, but it will cost around £52,000 for the procedure and initial aftercare.
His parents Nicola and Paul Harper of Whitwood, aim to raise £100,000 to support Cameron’s needs over the next ten years.
Mr Harper will be tackling the marathon cycle ride with family friends John Hodlin and Craig Robinson.
Mr Hodlin, 37, said: “The whole community has pulled together over the years to help support Cameron and his family.
“We came up with the sponsored cycle idea at Christmas and have followed it through.
“We’ll be setting off from the Lake District, cycling 250 miles off-road for four days, then around 100 miles on-road to York and then another 70 miles from York to Castleford.”
When the trio complete their challenge at the end of June, there will be a large fundraising event on their return home.
Mr Hodlin said: “We’re just biking and more biking at the moment to prepare ourselves.”
They have already raised hundreds of pounds towards the operation and have received a lot of support from Castleford Tigers.
Mr Hodlin said: “They are backing us and helping out with sponsorship ideas.
“Cameron was taken onto the pitch at half time at a match and we had a collection for the fund. We are fundraising through the charity Tree of Hope which holds all the money we raise in an account to then distribute it to the hospital for the operation.”
