First day exploring. Loop hike from village of Pontresina. Made it to Alp Languard 10 seconds after first people got of the chairlift. Waited on the summit for a bit, but Piz Languard never made it out of the clouds, so went down and had lunch at the Georgy hut. On way down found myself going the same direction as the Bernina Ultraks trail race, so ended up running along with them. Then decided to add a bit more with climb of Las Sours. A well marked trail ends abruptly on the west peak. Then it was a long way back down, with more running down the Ultraks course, these guys were running all day (42k, 2600m vert).
