My climbing buddy Mark and his family, are good friends with Rory. I have met her a few times, and we were part of her cheering squad last year, at the UTMB race in Chamonix.
This is a superb 15 minute North Face video documentary of Rory Bosio running the 125 mile GR20 trail across Corsica. This is one of the greatest treks in the world with 46,000' of vertical.
