The Science of the Tour of Flanders' Steep Walls: Anaerobic Repetitions and Positioning Battles on the Koppenberg and Paterberg

A Classic Defined by “Steep Walls + Positioning”

The Tour of Flanders isn’t about who’s strongest on the flats—it’s about who can repeatedly explode on cobbled steep walls like the Koppenberg and Paterberg, while seizing the right position before entering them. Pogačar’s 2026 victory here (also part of his spring winning streak) came down to the combination of these two abilities.

The Double Challenge of Flanders’ Steep Walls

Positioning Before the Wall Matters More Than the Wall Itself

Approaches to walls like the Koppenberg are often narrow; riders caught behind get boxed in, forced to dismount, or lose their rhythm for applying power. So the key tactical battle in Flanders happens in the “500 meters before the wall”—a costly fight for position that shares the same principles as bunch sprint positioning (echoing sprint positioning).

Repeated Anaerobic Efforts: The Battery Must Be Burned Many Times

Flanders’ steep walls come one after another; each climb draws down W’, and the recovery between them is extremely short (echoing W’ and repeated anaerobic efforts in cyclocross). Those who still have battery left on the decisive final wall are often not the strongest on a single climb, but the best at managing W’ across the entire race—which is why neither pure sprinters nor pure climbers tend to win here (echoing the Monument power fingerprint).

Ability Checklist for Preparing for Flanders

• Anaerobic power on cobbled steep walls and power delivery under vibration (echoing cobbled power loss)
• Ability to repeatedly draw down and recharge W’ at extremely short intervals
• Positioning, fighting for position, and holding your place on narrow roads before the walls
• Fatigue-state explosive power after ~270 km of accumulated racing (echoing durability)

The cruelest truth of the Tour of Flanders is that half the result is decided before you even reach the steep walls—if you can’t get position, even the strongest legs will only sit on someone else’s rear wheel watching the opportunity slip away. It doesn’t reward the rider who climbs one wall fastest, but the one who gets positioning, repeated W’ usage, and fatigue-state explosive power all right across the whole day. Pogačar’s 2026 victory here was never just about the legs—it was about stacking all three together as a complete whole.
