Video: Ultrarunner Rory Bosio is Running on Empty on the GR20 Trail

Corsica’s GR20 trail is well known for being demanding and difficult, yet beautiful and rewarding at the same time. Most hikers spend two weeks walking in end-to-end, covering 118 miles (189 km) in the process. But ultrarunner Rory Bosio wanted to do it in 50 hours. This video is her attempt to do just that, and the challenges she found along the way.
