The administrative preparations leading up to the ground-breaking ceremony took three years. During this time, a community of interest was formed that included all the parties concerned, such as Trailnet, landowners, foresters, conservationists, the city authorities, etc. Together, the "Biel Trail" project was realized. Together, the "Biel Trail" project was realized and the trail was largely built by hand, with as little use of machinery as possible. The route was also designed to protect nature by making use of existing undulations, hollows and gullies in order to keep construction work to a minimum. This also reduces the need for track maintenance, as erosion has less surface area to attack.

Much attention was paid to information and safety. Signs at the start and end of the trail provide information on behavior and emergency assistance. At junctions, the route has been routed so that bikers have to ride more slowly. Signs warn of difficult spots and show less experienced riders the way around them.

The local recreation area of Biel is criss-crossed by attractive single trails where mountain bikers like to let off steam. You can imagine that these are not the closest friends of people who are looking for a few quiet moments on the same trails. The Biel Trail defuses the user problem by channeling the mountain bikers. Because the trail is very attractive and challenging, and the different lines make it suitable for beginners and experts alike, it should attract mountain bikers like a magnet.
