Suzanne Baxter, from Michaelston-Y-Fedw near Newport, will take on Pen y Fan as part of the Tŷ Hafan Welsh 3 Peaks Challenge, in tribute to her son Harry, who died in 2019 at the age of 18.
Harry had Mowat Wilson Syndrome, a rare condition which caused severe developmental delays, unstable epilepsy and complex health issues.
He spent about 12 years under the care of Tŷ Hafan, which Ms Baxter described as his “happy place”.
Ms Baxter said: “Climbing a mountain for Tŷ Hafan seems minuscule in comparison to the many metaphorical mountains that Tŷ Hafan has helped our family climb.
“My team of trusty supporters have vowed to drag me over the finish line.
“Tŷ Hafan is certainly the most deserving cause to justify exhaustion, tears, grit and determination.
“We can never repay Tŷ Hafan, but if our team Harry’s Bluetits can raise a little more money for Tŷ Hafan due to our Pen y Fan efforts, then our efforts will be worthwhile.”
The challenge is especially significant for Ms Baxter, who has endured four hip replacements in the past 18 years.
James Davies-Hale, head of fundraising for Tŷ Hafan Children’s Hospice, said: “To read Harry’s story is humbling and really brings it home to me why Tŷ Hafan Children’s Hospice exists.
“Frankly I’m in awe of Suzanne for her grit and determination to take on Pen y Fan for this year’s Welsh 3 Peaks given her own health challenges that she has faced.
“I’m so grateful to her and her Harry’s Bluetits teammates for everything they are doing for us.
“Because when a child’s life will be short, like Harry’s, no family should have to live it alone.”
