January 23, 2017, Sunny Stroeer did the ascent from Plaza de Mulas in 8h47m, shaving 29 minutes off the women's ascent record. Wanting to keep her legs fresh for a longer speed attempt later in the week, Stroeer decided to walk down from the summit, rather than challenge local guide Chabela Farias’ roundtrip record of 12 hours and 40 minutes.
Aconcagua (6,961 meters, or 22,838 ft), located in the Andes mountain range, Argentina, is the highest point in both the Western Hemisphere and the Southern Hemisphere. It remains a much sought-after and formidable challenge for modern-day mountaineers. adidas Outdoor athletes Elizabeth "Libby" Sauter and Suzanne "Sunny" Stroeer are currently (Jan. 23, 2017) on the mountain, training for an attempt on the team speed record, from the park entrance to the top. On Saturday, Jan. 21, Libby left Camp Nido (Camp 2) and summited in a quick 7:45, typically a 12 hour trek. Monday, the 23nd, as Libby rested, partner Sunny threw down a training run from basecamp to the summit, taking 8:47 and breaking the existing female base camp to summit ascent speed record by 29 minutes The ladies subsequently launched two attempts on the long speed attempt from the trailhead to the summit and back(~40 miles roundtrip and 16,000ft of climbing), but were forced to turn around short of the summit both times.
