All participants in MARATHON DES SABLES 2019 will carry a SPOT®, Gen3 – a pocket-sized personal GPS messenger. Thanks to SPOT®, the MARATHON DES SABLES organisers will be able to follow the GPS position of all runners in real time. If a participant has a problem, such as an injury, one press of the button immediately alerts the emergency services and transmits his or her GPS coordinates so that rescuers can rapidly get to the runner’s location. SPOT® devices have been used in over 5,000 rescues around the world and brought peace of mind to many thousands of others.
