Most people take about a week to climb Mount Kilimanjaro. Erin Ton did it in under six hours. The 29-year-old Colorado runner set a new women's fastest known time (FKT) on Africa's highest peak on September 8, reaching the 19,341-foot summit of Uhuru Peak in 5 hours and 47 minutes — a full hour and five minutes faster than the previous record held by Kristina Scho Madsen.

Ton started in the dark from Mweka Gate, the quickest route up the mountain's southern slopes in Tanzania at 5,380 feet. Her route covered 26.38 miles and roughly 14,000 feet of climbing, passing through the rainforest — where howling monkeys accompanied her headlamp-lit start — then the arid high country, then past Barafu Camp at 15,000 feet before a final rocky ridge push to the top. The run wasn't glamorous: dust left her nose bloody by Mweka Camp, and altitude sickness hit her at Barafu, unusual for a runner who considers altitude her strength. Her round-trip time of 8 hours and 33 minutes also broke Fernanda Maciel's previous record of 10 hours and 6 minutes.

Part of what makes Kilimanjaro special is that it packs five climate zones into one climb — tropical jungle, alpine desert, and finally snow and ice near the summit on what is the world's largest free-standing mountain. Ton compared the high terrain to Colorado's alpine country, though her reconnaissance hike days earlier had required three puffy jackets thanks to fierce winds on the ridge. No technical climbing skills are needed, which is why the mountain draws so many trekkers — and why Ton started before sunrise to dodge the crowds.

The Kilimanjaro record is Ton's second of the Seven Summits, the highest peaks on each continent. She set a speed record on Aconcagua (22,837 feet) in Argentina in January, and her remaining list reads like an expedition catalogue: Carstensz Pyramid in Indonesia (16,024 feet), Denali in Alaska (20,310 feet), Mount Elbrus in Russia (18,510 feet), Mount Vinson in Antarctica (16,050 feet) and Everest in Nepal (29,031 feet). Denali in spring 2027 is likely next.

For regular travellers, the takeaway is that Kilimanjaro remains one of the world's most accessible big-mountain adventures — a week-long trek through jungle, moorland and glacier country that needs no ropes or crampons, just time to acclimatise. Ton's record is a fun benchmark, but her broader message is aimed at everyone: get outside, invite a challenge, and see a bit more of the world. Whether you're moving at record pace or ambling to Barafu Camp, the mountain's stacked ecosystems make it one of the most varied single treks anywhere on the planet. Story via Outside Online.
