The occupation of Western Sahara is a question of a forgotten colonization with a very limited framework of international recognition, media acknowledgment and talks. To break the remaining silence and invisibility, human rights activists have developed different initiatives, shedding light on the current situation of Western Sahara. This study investigates the Sahara Marathon campaign, an international sport event that has been developed in the Western Sahara refugee camps of Smara, El Aaiún and Auserd for twenty consecutive years.  Framing the Sahara Marathon as a case study, this degree project aims at inquiring into the potential impact and long-term implications of the international sport campaign, seeking “if” and “how” it contributes towards a social change and an end to the enforced invisibility of “Africa's last colony”, (Güell, 2015). In particular, this qualitative study examines the participatory approach and community engagement promoted through the campaign as well as the awareness-raising and dialogical processes triggered as a result of the Sahara Marathon sport event. The study is grounded on 23 in-depth interviews that have contributed to the external reliability of the research, underlining the reflections shared by organizers of the Sahara Marathon, drivers, freelancers, runners and most importantly human rights activists from Western Sahara. Findings reveal that the Sahara Marathon campaign raises awareness about the current situation in Western Sahara, contributing to a transnational acknowledgment of the conflict. The study also shows that active listening and convivial experiences are promoted throughout the campaign, dismantling stereotypes among communities coming from abroad and Saharawi people living in the refugee camps. In terms of participation, it has been concluded that the campaign uses a participation by consultation approach, needing a new model to showcase the utility and effectiveness of the event as well as to ensure its sustainability in the future.
