Long stretches of road near Brussels?

Can anybody help me here- is there anywhere near brussels where you can ride 10-15 minutes without crossing a busy road, getting a red light, or having to go through all kinds of turn-offs and stop signs? It's great that there are bikepaths everywhere, but they are often useless for doing TT intervals of more than 5 minutes, especially when shared with joggers, people walking dogs, etc.

I've mostly ridden to the canal road between Leuven and Machelen, but that already takes a good 45mins, and you are lucky to get 8 minutes without having to cross traffic.

Are there better options SW of the city?

No.
Belgium is a bit too crowded for that. Some parts of the Belgian towpaths are not interrupted for over 10 km or so. E.g. the stretch between Zwijnaarde (Ghent) and Oudenaarde along the Scheldt. The same for the stretch between Gentbrugge (Ghent) and Wetteren.

Thank you for your answer- That's too bad. Guess I'll just have to adapt and do shorter sessions...

Along the same lines, you seem to know the cycling in Belgium really well so I'd like to hear your point of view: Supposedly Rabobank use a climb near La Roche en Aredenne for FTP tests from time to time- Baroque en Fraiture I think? Do you know this, or know of any climbs in southern Belgium that would be 15-20 minutes?
