Julbo, the French manufacturer of sports sunglasses, has sent three of its own employees to participate in two of the four races of this year’s edition of The North Face Ultra Trail du Montblanc, of which it is a sponsor. Both races were interrupted because of bad weather, but all three Julbo officials ended the respective races. They were Nick Yardley, who runs Julbo’s U.S. subsidiary; Bertrand Ragonneau, responsible for the German and Austrian markets; and Guillaume Arnoux, product manager.
