Official event pageWhat this race demands
This 235-kilometer single-day ride demands exceptional muscular endurance and pacing discipline to cover an ultra-distance route.
Ultra-Distance Endurance
Covering 235 kilometers requires a high level of aerobic conditioning and the physical resilience to sustain output over many hours in the saddle.
Muscular Durability
The sheer length of the ride places continuous stress on the supporting musculature and joints, demanding strict attention to bike fit and pedaling efficiency.
Given the extended duration likely exceeding seven to eight hours, athletes should aim for a consistent intake of 60 to 90 grams of carbohydrates per hour to maintain energy balance.
