On the 17th of May 2014, South African explorer Mike Horn and Swiss mountain guide/alpinist Fred Roux reach the summit of Makalu without the use of additional oxygen or high altitude porters. Mike Horn and Fred Roux left advanced base camp at 5'700m at midday on the 16th of May and climbed that afternoon to their first camp at 6'800m. The following day they climbed up to 7'500m, stopping for some hours rest before doing the summit push to 8'463m in the early hours of the 17th of May. The two men took on their own rhythm during the ascent, eventually separating and continuing on their own. Fred Roux reached the summit first at 10:30 local Nepalese time, some hours before Mike, who arrived at 4 o'clock in the afternoon. Yet another full day was ahead of them as they started the descent and eventually the exhausted but happy team greeted each other once again in Makalu's advanced base camp. Mike Horn and Fred Roux are the first men to successfully climb a Himalayan summit over 8'000m in the Nepal 2014 climbing season and are two of three men in history who have summited this mountain without the use of additional oxygen. "The climb was particularly grueling for both of us. We were both very fit and well acclimatised after 3 weeks of waiting for a good weather window, but the mountain is extremely exposed and challenged us with its strong winds and very cold temperatures. We are thrilled to have both reached the summit. It's a great achievement of physical and mental endurance and we are thrilled to be rewarded with this magnificent victory", says Mike.
