AI quick summary
- The Tour of Flanders (De Ronde) is the cobbled Monument of Flanders, ~260 km in early April with ~20 cobbled climbs (bergen). It's the second Monument of the season and the biggest race in Belgian cycling
- The bergs: short (0.5–2 km), steep (up to 20%), and cobbled. The Oude Kwaremont, Paterberg, and Koppenberg are the most decisive. The Koppenberg is so steep (22% max) that riders often have to run up it
- The race rewards the strongest rider in the peloton — the bergs filter the field relentlessly. By the final climb, only a handful of riders are left. Tactics: position before the bergs (start each climb near the front) and save energy for the final 40 km
- Most wins: Achille Buysse, Eric Leman, Fiorenzo Magni, Tom Boonen, Fabian Cancellara (3 each). Recent: Van der Poel (multiple), Pedersen

| Oude Kwaremont | 2.2 km | 4.2% | 11% | Cobbles |
| Paterberg | 360 m | 12.9% | 20% | Cobbles |
| Kruisberg | 2.5 km | 4.6% | 9% | Partially cobbled |
| Taaienberg | 630 m | 7.4% | 15% | Cobbles |

How the race unfolds
De Ronde is a race of elimination. The bergs, coming in rapid succession in the final 80 km, filter the peloton like a sieve. By the time the race hits the Oude Kwaremont for the final time (17 km from the finish), only 15–20 riders remain. The final selection happens on the Patterberg (13 km out) — the last cobbled climb, steep enough to split even the reduced group.
The winning move: typically a solo attack or a small group that forms on the final passage of the Oude Kwaremont or the Patterberg. The rider who can produce the most watts on a 20% cobbled climb, repeatedly, in the final hour, wins Flanders. It rewards not just fitness but bike handling (riding cobbles at race pace is a skill) and positioning (starting each berg at the front, not fighting from the back).

The Belgian passion
Flanders is Belgium's biggest sporting event. Millions line the route, many dressed in club jerseys, drinking beer, eating frites, and ringing cowbells. The atmosphere is more like a football match than a bike race. The bergs are lined 5-deep with fans — you can't see the road for the crowd.
This passion shapes the race: Belgian riders feel the pressure and the glory of winning their national Monument. Tom Boonen (3 wins) and Fabian Cancellara (3 wins) are Flanders royalty. In the current era, Mathieu van der Poel (whose grandfather Raymond Poulidor was a Flanders hero) carries the legacy.
