About Mummelsee
The Mummelsee lies below the Hornisgrinde, the highest mountain of the northern Black Forest, on the Black Forest High Road. From Seebach it climbs steadily through dense 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.
