Nancy lives in the Providencia neighborhood of Santiago. She jogs three times a week, and she doesn't even stop as she tells us about her experience with the long bike and pedestrian path where she runs regularly.

A women's marathon awaits her in two weeks, and she doesn't want to be unprepared.

She likes this city trail, made by Grupo Costanera, because it is safe, uninterrupted and very well run. She has been coming here to run for four years now, even in the evenings.
