The main event sets off at noon on the last Saturday of this month from Reef machair for a circuit around the Bhaltos Peninsula in Uig, Lewis.
Supporters from across the world can join in by completing their own 10k distance wherever they are.
Registration is at www.lindanorgrovefoundation.org.
Linda Norgrove was kidnapped in Afghanistan where she was working as a humanitarian aid worker and subsequently lost her life during a failed rescue attempt in October 2010.
The foundation set up by her parents, John and Lorna Norgrove, aims to continue her work in Afghanistan.
It helps improve the lives of women and children in the country where one in five women are widowed and most recent statistics show that illiteracy amongst women is a startling 88%.
One project the charity is involved in is tackling the shortage of female doctors in Afghanistan. Women face not receiving medical attention when required as they are forbidden from seeing a male doctor.
University scholarships have previously been provided for nine girls to study medicine. This year a further 11 students have started training.
A spokesperson for the event said: “This is our biggest fundraiser of the year and all proceeds will go towards helping women and children affected by the ongoing hostilities in Afganistan.
“All ages and abilities welcome, make it a family outing or challenge yourself for your personal best. ”
The Linda Norgrove Foundation’s biggest annual fundraiser takes place in two weeks.
Money raised from the 10k run / walk on 30 September will go towards scholarships for Afghan women to study to become doctors.
