Everyone can monitor the progress of each runner through a free Facebook application.
For people that do not want to use a Facebook app there is a SMS update system.
The prescription of using this system has not been released yet. Check before the races begin.
There are no available places for people to sigh up. The 2014 Trail des Aiguilles Rouges is oversubscribed and has found its 600 participants!
