The team – ranging in age from seven to 42 – hope to raise funds for charity Steel Bones to enable continuous support given to individuals and families that have suffered limb loss across the UK.
The challenge will take place on May 30 and see Matt Furze, 36, Jorja Furze, 12, Emma Joy-Staines, 33, Leigh Joy-Staines, 36, Teddy Joy-Staines, seven, Cheriee Wales, 38, Peter Wales, 42 and Jesse Wales, eight, take to the mount.
Heading up the challenge will be Paul Clark, who became an amputee just last year, and after having surgery in 2014 had a major bone infection, which resulted in the loss of a limb.
Leigh Joy-Staines, founder of Steel Bones UK, said: “There are around 5,000 amputations taking place in the UK every year leaving people in a very lonesome situation.
“Speaking as an amputee myself, I know how hard it can be to do normal, everyday tasks that so many people take for granted. This is why we are so proud of the families who are pushing the boundaries and climbing Mount Snowdon, in an effort to raise money for Steel Bones UK.”
