Startingpoint: Domein Bovy  Galgeneinde 22  3550 Heusden-Zolder
This is the larger hub. It's the combined Mtb track from the official Bloso site. Green AND  the blue arrows. In my opinion the blue parts are the most interesting.
I've recently corrected the first blue extension because it was the most difficult to ride with Gps in the summer. The second blue hub I will check later on, but I dont think this will be a problem. You know .. sometimes watch the nature and the arrows
