La Ruta El Cinto Cruz is a great off-road running opportunity just outside the city. This open air cycling path runs along an unnamed road beginning from Parque Metropolitano Chilibulo in Lloa. The first 10 km travels through flat pastureland to the Torohuco water plant, which has a great, uncrowded view of Quito. We recommend turning around here.
For a real challenge, continue along the trail as it steepens to a challenging 9-10 km ascent up to the top of the Teleférico. The grades here can be 9-10% — a real challenge already at 3300m. At the end of the trail, connect with our route on the ridgeline of the Pichincha Volcano. See that route here.
