Herman van der Westhuizen completed a 15-minute training swim in the middle of a 80 km per hour wind storm at 5,100 meters.
He is part of the Madswimmer expedition of 7 South African high-altitude swimmers, 2 medics, 4 support climbers, a tour guide and a cameraman were rising to the challenge – steadily towards the world’s highest altitude swim on Mt Ojos del Salado in the Andes Mountain.
