Expert is the level of the ITRS trail rating that does not forgive misjudgement. The steepness demands surgically precise braking and perfect line choice. Jumps often have no alternative (roll-in) and require secure in-air technique.
| Gradient: | > 70% |
| Type: | DH / Freeride |
| Jumps: | Massive |
| Risk: | Extreme |
The top of the ITRS trail rating is for professional riders only. The terrain is extremely steep and technical, right at the limit of what is rideable. It demands specific DH gear and years of experience in the toughest conditions.
The terrain beside the trail is flat, gently sloped or covered in soft vegetation. A fall results only in surface injuries (scrapes). There is no risk of tumbling.
Steep terrain beside the trail, but with obstacles such as trees or bushes that can stop a fall. There is a risk of minor injuries. Getting back to the trail unaided is possible.
Ravines or slopes of more than 4 metres with no vegetation to stop a fall. A fall can cause serious injuries and requires intervention by the mountain rescue service (GSS).
Vertical cliffs with no obstacles whatsoever. A fall is almost certainly fatal or leaves permanent, critical consequences. Only for riders with perfect control of mind and body.
