What this race demands
This 200 km spring gravel grinder demands sustained endurance and significant climbing capacity across 3100 meters of elevation gain.
Aerobic endurance
Completing a 200 km distance requires an engine capable of sustaining steady output for many hours in the saddle.
Climbing volume
Accumulating 3100 meters of elevation over the route necessitates efficient climbing mechanics and pacing discipline.
Spring durability
Riding long distances early in the season demands resilience against potentially cold and wet conditions in Northumberland.
Due to an expected duration exceeding 2.5 hours, athletes should target 60 to 90 grams of carbohydrates per hour to maintain energy levels.
