 
      KNRM, The Royal Netherlands Sea Rescue Institution, used SafeTrx Flotilla as an event tracking
        website for the 2017 West Coast Challenge and 2018 West Coast Challenge, a running and biking marathon for duos
        and solo runners over 130 kilometers from Den Helder in the north of Holland to the Hook of Holland in the
        south. 
        Participants used their SafeTrx app to report their location every 10 minutes with the SafeTrx Flotilla website
        displaying the locations of all participants.
