Described by Jojo Klein:

Starting at the cablecar station of the 'Nebelhornbahn' in the valley, the goal is to clap the cross at the top of the Rubihorn and going all the way back to the cablecar station.

There is no route or way predetermined. Just follow the fastest track you can find. The only importance is to start at the Nebelhornbahn in the valley, clapping the cross at the top of the Rubihorn and running back to the start. 

Here in Oberstdorf, we call this challenge 'Rock the Rubi'. 

You can start anywhere along the route, which is about 100 miles with 14,000' of cumulative elevation gain.  This is described counter-clockwise, starting in Soufrière at the Primary School. From the gate, turn left on to Palmiste street. Turn right on Cemetary Road, cross the Soufriere River, turn left on Desmond Avenue, turn right on Church Street and continue through town. Follow the main highway to Bellevue Farmers’ Co-Operative (Myers Bridge). Bear right to Victoria Corners. Continue to Choiseul and pass through the village of Piaye to Laborie.

The route follows the trail of "Norge på tvers" (Norway across, https://www.norgepatvers.no/), a trail marked by The Norwegian Trekking Association (DNT) which starts at the Swedish border at Sylsjøen and ends near the ocean at Stjørdal. The trail passes six cabins owned by DNT, and is a popular seven-day hiking trip during summer.
