You step out of the minivan at 3,800 m, wind pressing against your jacket, and the high plain opens toward Cotopaxi’s cone — snow rimmed and uncompromising. Over three days this multisport run threads high Andean páramo, cloud-forested descents and the jungle gorge of the Pastaza River: a short, thin-air hike to José Rivas refuge; a long downhill on a cross-country bike that plunges through Llanganates’ mist into views over Baños; a class‑3 raft that throws you against volcanic rock walls; and a technical canyoning set of waterfalls deep in Sangay National Park.
