F3 Leuven–Brussel

The F3 connects Brussels with Leuven via a fast, paved cycling route. Expect mostly asphalt, with some concrete, cobblestones, and a touch of cobbles here and there. Most of the route runs on segregated cycle paths, alternating with quiet streets; only on the city edges do you encounter short sections of busier roads. The profile is gently rolling and easy to ride in both directions.

Ideal for commuting, training, or a quick weekend ride between the capital and the university city. You'll pass through suburban zones and stretches of open countryside without detours. Start in Brussels or Leuven—the route works perfectly both ways.

In short: a comfortable, clear through-traffic cycle connection with plenty of asphalt and only occasional shared or busier segments.
