The organizers of GM4O visited the office of VMNRIC in Barcelona on 21th January 2012. Their offer to participate in the Cup Grand Prix of the Nations 2012 was as a mystery for us, for this reason we decided to meet Mr. Francesco Serra and Mr. Lluis Aloiy Barguet in their office in Barcelona. The association with enthusiasm of volunteers gives their best to promote and popularize mountain running. All other matters concerning the organization have been acceptable for us and we have accepted the invitation with a pleasure. We are glad to be a part of eminent mountain races in Europe.
