About Ofen Pass
The Ofen Pass (2149 m) runs right through the Swiss National Park into the Val Müstair. From Zernez the road climbs moderately through pine and stone-pine forest.
In rampida you ride the route exactly as it lies on the road: the gradient reaches your trainer metre by metre, the scenery is built from real elevation data and OpenStreetMap. A pacer group can pull you along, and next time you race your own ghost.
