Official event pageWhat this race demands
The Delirious WEST 100 & 200 Miler demands sustained multi-day physical endurance and mental resilience to traverse 178.4 kilometers of forests and ocean cliffs with 3785 meters of elevation gain.
Ultra Distance Endurance
Covering 178.4 kilometers requires pacing strategies designed for multi-day continuous exertion and deep aerobic resilience.
Climbing Volume
Accumulating 3785 meters of elevation gain across coastal cliffs and forest terrain demands continuous lower-body strength and efficient uphill movement.
Terrain Adaptability
Traversing the Bibbulmun Track across mixed surfaces of forest paths and ocean cliffs requires technical footwork and durability under fatigue.
Given the multi-day nature of the event lasting well beyond standard ultra distances, athletes must maintain a consistent carbohydrate intake of 60 to 90 grams per hour to sustain energy output.
