Before flying into Antarctica, the group will meet at Cape Town, South Africa.
For an ultra marathon in extreme conditions, a strategic layering system is essential. It balances warmth and insulation with lightweight, breathable materials, ensuring you stay comfortable and agile throughout the endurance challenge.
Apart from running, enjoy an ice-tunnel expedition, a visit to the emperor penguin colony, the sauna, hiking, golf, and many more unique experiences during your time in Antarctica.
