Signposting and difficulty levels, for a safe cycling holiday
Signposting and difficulty levels
Blue route - easy Family-friendly cycle trail with a good surface (fine gravel or comparable surface) which can also be ridden on standard bikes. Inclines and descents of between 0% and 5 %, on short sections a maximum of 10%. Alternating climbs and descents; no continuous climbs. Traffic free, or not much traffic. No specific danger areas; any danger areas are made clear (e.g. signposting).
Red route - moderately difficult Requires sports-level cycling ability and particularly aggressive riding. Mountain bike equipment recommended. Inclines and descents of between 5% and 12%, on short sections a maximum of 17%. There may be sections of the route where visibility is not great and where there are plenty of bends. Be prepared to meet vehicular traffic which takes up the entire road. The road, in particular the surface conditions, drainage facilities (e.g. water coils), cut-off areas (e.g. barriers), safety installations (e.g. missing railings and fences) and information about danger points are solely intended for work vehicles including tractors and lorries. Such facilities may also present danger sites for cyclists.
Black route - difficult Difficult, challenging mountain bike route which has numerous points where the maximum incline exceeds that of the red route and whose route characteristics are even more difficult. Mountain bike equipment obligatory. Riding which is appropriate to the conditions is required.
Single Trail - extremely difficult Extreme and challenging route; no longer passable by vehicles. Character of an alpine path, with all the alpine dangers. Risk of crash; no safety facilities such as railings; very steep. Be prepared to encounter obstacles, such as high layers, roots and boulders. Not always rideable; in some sections you may have to push or carry the bike. Due to the weather, these routes are often only passable with extreme care.
