Singletrail at the foot of Mettenberg No. 13

This training route initially leads to the marble quarry above the well-known glacier gorge. From there, the trail climbs to Pfingstegg, where there is a family-friendly restaurant with a playground. Those who want can also take the gondola back down to the valley here. To run the entire 13.5 kilometers, follow the trail that goes through the 150-meter-long Breitlowina tunnel. Afterwards, it continues via the Vitaparcours back to Grindelwald. With a northern orientation, the route is especially suitable in the height of summer when all snowfields have melted.
