What this race demands

Ultra Distance Capacity
Covering 300 kilometres requires sustained aerobic efficiency and high resistance to muscular fatigue over many hours in the saddle.
Late-Season Durability
Taking place in October, the event requires pacing strategies and physical resilience to maintain output across potentially cooler autumn conditions.
A target of 60 to 90 grams of carbohydrates per hour is recommended to sustain energy levels across the extended duration of a 300-kilometre ride.
