The 80K Oso is 76 km with 4,400 m of climbing from the cloud forest of Mindo, past the Las Palmas Rio Blanco Reserve and Cruz Loma, down into Quito's historic centre.
The organiser describes trails that cross rivers and ravines at the foot of the Pichincha volcano, a climb towards the Las Palmas Rio Blanco Reserve with views of the Lloa valley, then Cruz Loma and a descent into the historic centre, where “mountain and history converge”. The route reaches the high-altitude paramos of Pichincha, home of the Andean bear. Gun time is 01:30 on Saturday 31 July 2027 in Mindo, with 20 hours allowed.
