The Sydneysider set out to climb Middle Brother Mountain 17 times by bike on Saturday, May 4.

Russell said everesting is an activity where cyclists ascend and descend a given hill multiple times, in order to have cumulatively climbed 8848 meters (the elevation of Mount Everest).

"Everesting is considered the most difficult climbing challenge in the world," he said.

Russell said he was inspired to raise money for the Aminata Maternal Foundation (AMF), to help women in Sierra Leone gain access to better healthcare.

"One in eight women die as a result of pregnancy-related issues," he said.

"A child born in Sierra Leone is 200 times more likely to die than if it was born in Australia."

On Saturday, May 4 Russell everested through low temperatures and unforeseen heavy rainfall.

Russell said he was not only wet, but freezing cold and shaking uncontrollably as he tried to navigate the rivers of water, gravel and mud on the ascents and descents.

The gruelling conditions not only meant extreme physical adversity but also caused major mechanical bike issues. Russell completed the final third of the challenge on his wife's mountain bike.

Russell's mother grew up at Coopernook and walked up Middle Brother Mountain frequently.

Russell said his sentimental ties to Middle Brother were an important part of his everesting experience.

Russell's eight-year-old son Jett was keen support to his dad's feat and joined him for one ascent of Middle Brother.

Despite the challenges encountered during the event, Russell said it was an enriching experience and rewarding to share it with his family.

"We supported each other in ways that we didn't know was possible," he said.

"We feel privileged to have been able to partner with AMF to be able to do our bit to change or save someone's life.

"It's an experience that we will never forget"

Russell took 32 hours (22 hours moving time) to complete the challenge of 203 kilometres.

The ascent would have been over the height of Mount Everest.

The Stokes family has helped to raise over $5000 for AMF.
