Details surrounding the final moments before Gugu Zulu's untimely death are trickling in as the nation mourns his passing.
The 38-year-old race car driver, accompanied by his wife Letshego, died while attempting to summit Mount Kilimanjaro in support for the Trek4Mandela campaign.
702's John Robbie spoke to physiologist, Dr Zac van Heerden, regarding some of the challenges climbers face when summiting the highest peak in Africa.
Van Heerden said he doubts that Zulu had meningitis and could have suffered from mountain sickness or altitude sickness, which is not the kind of illness that should kill.

The flu-like sickness are things that happen due to exposure due to the altitude... The flu-like symptoms are something that has to be dealt with.— Zac van Heerden, physiologist
Van Heerden expressed concern over the route that was selected for the expedition, which has a 22% success rate.
Summiting that particular route in 4 days is something that bothers me as well. That means he's climbing 1 000 metres per day to get to the summit. I think they were rushing it.— Zac van Heerden, physiologist
