The climbers who summited Mount Kilamanjaro for Trek4Mandela initiative received a hero's welcome at Orlando Tambo International Airport on Wednesday evening.
While they achieved their mission, their hearts were heavy after the death of race car climber, Gugu Zulu.
Zulu died on Sunday while being rushed to hospital after attempting to reach Uhuru Peak. He had suffered 'flu-like' symptoms and had difficulty breathing.
702's John Robbie spoke to the expedition leader, Sibusiso Vilane, about what happened during the climb up Africa's highest peak.
Listen to the conversation below:
Vilane said a doctor examined the 38-year-old after he complained about a sore throat.
All climbers I was with were aware that there will be symptoms that they need to let me know of so I can make a decision with a doctor. But I never heard anyone telling us of anything.— Sibusiso Vilane, Mt Kilamanjaro expedition leader
