JACQUI King, from Mirfield, is facing her challenge of a lifetime in September.
That is when she embarks on a sponsored Inca Trail trek to Peru to raise money for leading veterinary charity the PDSA.
Jacqui is taking part in the fundraising trek in memory of her son's dog, Stella, who received veterinary care from PDSA for food poisoning.
Jacqui, 40, is appealing for support from local animal lovers to help raise the £2,650 in sponsorship she needs before she can start her 10-day hike through the diverse, mountainous country. The challenges she will face include climbing 4,200 metres of steep, narrow mountain trail to a renowned landmark, Dead Woman's Pass, whilst adjusting to the rarefied air of the climb.
She will also spend a total of more than 30 hours on foot, travelling through dense cloud forest and green valleys.
She said: "This is the first time I'll have done anything like this, but I am determined to show my gratitude to PDSA after they cared for my son's dog Stella.
"Animals have played an important role in my family's life and I want to help others who cannot afford private veterinary care for their pets."
People wishing to sponsor Jacqui can send a cheque for her attention, payable to PDSA to 1 Lorne Street, East Bowling, Bradford, BD4 7PS.
