I didn't have high expectations for a run starting near a dam, assuming the human imprint would make the run seem less adventurous, too close to civilization. I suppose all of Switzerland is fairly civilized - even in remote valleys, you can access public transport, restaurants, huts, and a cell signal. But I'm continually amazed by the wild and rugged energy of peaks you can reach by running, and then drop down from in almost no time. I prefer a run that feels far away and lands you alone on a mountain. This one, to my surprise, did exactly that. The run and scramble up to Pigne de la Lé is one of my unexpected favorites. If you happen to catch a dramatic sunset from the summit, the run goes from awesome to indescribable.

This is a run so good you might just stay and do it again the next day. We did.

The trail along the Val de Moiry leading back above the dam may be some of the smoothest, fastest kilometers you can find in the Alps. Savor these!
