Darwin Atapuma of BMC has won the fifth stage of the Tour De Suisse.
A 126.4km stage from Brig-Glis to Carì on a day for the climbers which would test the resolve of race leader Peter Sagan with two 2000m+ mountain passes - the Furka and Gotthard and a summit finish.
Matvey Mamykin (Katusha), Riccardo Zoidl (Trek-Segafredo), Michael Mathews, Amets Txurruka (Orica-GreenEdge), Darwin Atapuma, Silvan Dillier (BMC), Ian Boswell, David Lopez (Team Sky), Bram Tankink (LottoNL-Jumbo), Kristijan Durasek, Jan Polanc (Lampre-Merida), Laurens Tean Dam (Giant-Alpecin), Joseph Dombrowski, Davide Villella (Cannondale), Tim Wellens (Lotto Soudal), Kantstantin Siutsou, Natnael Berhane (Dimension Data), Laurent Pichon (FDJ), Dries Devenyns (IAM), Hubert Dupont (AG2R La Mondiale), Winner Anacona (Movistar), Pieter Weening, Antwan Tolhoek, Michel Kreder (Roompot) got into a break and were 1.30 ahead after Peter Sagan had crashed but got back into the peloton.
KOM leader Antwan Tolhoek took the twenty points on the Furka climb and after 57kms, the lead of the front group had gone out to 2.30 but was down to 1.44 with 44kms to go.
Jan Polanc, Wellens, and Atapuma managed to free themselves from the rest of the front group and Wellens took the points on the intermediate sprint.
With 5.5kms left, Darwin Atapuma attacked and was twenty seconds clear of Polanc and Wellens.
The peloton tried to chase down the BMC rider but Atapuma stayed way and won in a time of 3:41:51, four seconds ahead of Warren Barguil of Giant-Alpecin and seven seconds ahead of Pierre-Roger Latour of AG2R La Mondiale.
That third place meant that Latour now leads the race from Wilco Kelderman.
