This is like magic eye
If you were to divide the picture into four sections, the trail would traverse diagonally across the top right section, from bottom right to top left. It’s clearest where you can see squiggly singletrack, above the fir tree to the right of the road (the fir tree is pointing at it). That road is not a “road”, by the way, but the top of a truly enormous dam.
The trail descends from the ridge at the top (i.e. the horizon), to just out of shot to the right, on the road. The penalty for failure is the big drop to the rider’s right (into a gorge, the Barberine gorge). It reminds me rather of the bridge-crossing scene in Holy Grail (“what is your name, what is your quest, what is your favourite colour etc.”).
