Gary will be setting off on a 12 day adventure as part of a group of 18 with the aim of raising as much money as possible for charity.
His chosen charity is Crohn's and Colitis UK and all the money raised will go direct to the charity to help fund the good work they do to support the disease sufferers.
The former Berwick High School pupil said: "Many of you will know why the National Association of Crohn's and Colitis (NACC) is very close to my heart.
"My younger brother, Kevin, is a long term sufferer and continues to be a conqueror of Crohn's disease.
"I have looked on in admiration as he has coped quietly and bravely with many challenges over the years.
"I wanted to raise some money for the great work NACC do in assisting sufferers throughout the UK and providing funds for research projects into a disease which is still challenging medics and researchers."
Gary, 30, was keen to undertake a major challenge for charity having just completed three years working abroad in Sydney, Australia.
Kilimanjaro, is an inactive volcano in north-eastern Tanzania and is the highest mountain in Africa at 5,893 metres or 19,334 ft above sea level.
Only 40 per cent of climbers actually reach the Uhuru summit with the majority of climbers turning around at Gilman's Point, 300 metres short.
Gary is determined not to be part of that statistic and has set himself a target of 2500.
He is well on the way and has already raised 1700 but would appreciate more support.
He has a Just Giving internet page at www.justgiving.co.uk/gary-wyse and any donations will be gratefully accepted.
Crohn's and Colitis UK aims to improve life for everyone affected by Inflammatory Bowel Disease (IBD), the most common forms being Crohn's Disease and Ulcerative Colitis. Together these conditions affect about 250,000 people in the UK.
