Marathon des Sables
The Marathon des Sables (MDS) is one of the world's toughest multi-stage ultramarathons, taking competitors deep into the Moroccan Sahara across hundreds of kilometres of unforgiving desert terrain.
While the event provides official GPS tracking for participants, GTC offers personal satellite communicators, emergency messaging devices and outdoor equipment to support your training, future adventures and life outside the MDS.
hARDWARE FOR THE uLTIMATE dESERT cHALLENGE
The Marathon des Sables has become synonymous with endurance, resilience and self-sufficiency. Covering approximately 250 kilometres over six stages through the Moroccan Sahara, competitors carry their own equipment while facing extreme temperatures, endless dunes and some of the most remote landscapes on the planet.
With little or no mobile coverage throughout much of the course, communication and preparation become an important part of every competitor's planning. Whether you're training for your first MDS, preparing for future desert races or simply looking for reliable equipment for remote adventures, GTC offers a carefully selected range of satellite communicators and outdoor essentials to help you prepare with confidence.
