What this race demands
This event demands exceptional climbing capacity and muscular endurance to complete 250 kilometers and 4400 meters of elevation in spring conditions.
Climbing volume
Accumulating 4400 meters of elevation gain across a 250-kilometer route requires sustained power output and efficiency on repeated ascents.
Muscular durability
Covering a distance of 250 kilometers demands profound resistance to fatigue and pacing discipline to manage energy reserves over a long day in the saddle.
Spring weather readiness
The April date in Belgium requires preparation for variable weather conditions, including potential cold temperatures, wind, and precipitation.
Given a likely duration well exceeding 2.5 hours, athletes should target 60 to 90 grams of carbohydrates per hour to sustain output.
