The South32 Rottnest Channel Swim is a 19.7km open water swim from Cottesloe Beach to Rottnest Island.
What this race demands
This 19.7-kilometer open water swim requires exceptional aerobic endurance and open-water sighting over an extended duration.
Extended Duration
Covering 19.7 kilometers in open water demands sustained aerobic output and mental resilience over many hours of continuous swimming.
Open Water Efficiency
Swimming across the channel requires consistent stroke mechanics and effective sighting without the benefit of pool walls or lane lines.
Marine Environment
The open ocean setting places high demands on thermoregulation, pacing discipline, and nutritional intake while under continuous physical exertion.
Athletes should aim for 60 to 90 grams of carbohydrates per hour through liquid nutrition or feeds from an accompanying support craft to sustain energy over the extended duration.
