Official event pageWhat this race demands
Levi's GranFondo demands exceptional sustained climbing ability and deep muscular endurance to manage 4,222 meters of elevation gain over a 222-kilometer road route.
Climbing volume
The 4,222 meters of elevation gain across the route require prolonged climbing efforts, demanding high sustained power-to-weight output on ascents like King Ridge.
Muscular durability
Covering 222 kilometers while navigating significant vertical change requires high resistance to local muscular fatigue in the legs and core.
Pacing discipline
The substantial distance and elevation profile demand strict adherence to conservative early-race pacing to prevent late-stage bonocking.
Given the duration required to complete 222 kilometers with over 4,000 meters of climbing, athletes should consume 60 to 90 grams of carbohydrates per hour to maintain energy balance.
