James Forrest has completed his record-breaking expedition in just two months.
The 35-year-old walked over 1,000 km in his mission to reach the peak of all of Ireland and Northern Ireland's 600 meter-high mountains.
Forrest revealed that he ascended the height of Everest every week for eight weeks in a row, completing the peak-bagging challenge solo and unsupported in 56 days.
He believes that the expedition is the first continuous ‘single round’ of the mountains of Ireland.
The full-time adventurer and travel writer also slept wild in the mountains in a small tent.

The Englishman counted Knocknadobar in County Kerry as his final summit last week.
"I feel on top of the world to have finally completed this epic expedition. It has been the adventure of a lifetime and an incredibly tough challenge, both physically and mentally," he said.
“Mountains are good for the soul. I love the freedom, the fresh air, the isolation, the unpredictability, the escapism – and this journey has let me experience these joys more than most.
“Ireland is an incredibly wild and beautiful country and I found the people to be so warm and friendly.”
Among the list of 273 peaks in Ireland and Northern Ireland that he reached are Carrauntoohil, Croagh Patrick and Slieve Donard...even in appalling weather conditions and despite Storm Ali.
MountainViews.ie founder Simon Stewart said, “We are delighted to see this achievement by James Forrest in completing the Vandeleur-Lynam list of the 273 Irish mountains over 600 metres. Despite bad weather he completed this in approximately two months, faster than anyone else we have on record.”
Forrest previously climbed all 446 mountains in England and Wales in just six months in 2017.
He hopes to write a book about his adventures in Ireland - following on from the success of 'Mountain Man' which recalls his English expedition.
"I faced such brutal weather during this challenge at times I felt like giving up," he said of the treacherous Irish weather. "But I persevered and was rewarded with some wonderful and poignant moments in the stunning landscapes of the Irish countryside."
“I was particularly wowed by the beauty of the mountains in the west and south-west of Ireland. I loved exploring those wild places – it was breathtaking.”
