Advice, tios, suggestions for road cycling in Belgium

Hi All,

I’m going to be staying near Brussels airport for a week with work and I’m taking the road bike.

Can anyone suggest any routes that I should look at in the area – I reckon on having a couple of hours in the evening to get out?

Looking at a map on Google I reckon I’m limited to the area between Vilvoorde and Mechelen.

Thanks
Paul
