Parcours on the Altenbergsteg bridge in Bern

Être Fort (“Be Strong”) parcours athlete Simon Gfeller crosses the Altenbergsteg bridge in Bern the hard way: by hand, across the underside of the iron framework. From Être Fort founders Roger Widmer and Felix Iseli:

Our aim is to unite people with a passion for movement, to share experiences and for the spirit of Parkour to be noticeable. According to the principle “être fort pour être utile”, we want to use our resources to provide assistance.
With One Percent For The Planet we have found the perfect partner for our mission. We donate 1% of our total annual sales to environmental organisations.”
