    Triathlon racing and events, in general, are in uncertain times at present. Our normal operations have been changed and new GPS technologies introduced to an event that provides a platform for participants to adhere to the current social distancing policies.

    Each participant is issued with an individual start time, a GPS tracker, and a swim tow float. Participants engage in the rolling start every 30 seconds and then follow there chosen distance via the course marking. The transition area will be adequately spaced out and interactions minimized. 

    The added benefit, of course, is that your friends and family can watch the action unfold on the live tracking pages (links provided below).

    The Olympic venue, Eton Dorney, offers pan flat, traffic-free roads, and a beautiful clear lake. The venue is private and specifically hired for the purpose of a traffic-free, public free triathlon event. 

    About GPS Tracking:

    Provided by Geo Tracks.

    Instead of using the traditional 'timing chip' the GPS tracker does the same job of providing results and split times but also allows your friends and family to follow your progress live! 

    The GPS tracker will be issued in a neoprene ankle bracelet much like the standard timing chip. For the swim section of the triathlon, the GPS tracker is put in a tow float (see the event information pack for more details on this).

    Using the GPS trackers and geofences (a virtual geographic boundary, defined by online coordinates, that enables software to trigger a response when a tracking device enters or leaves a particular area) timing points and results are provided without the need for any human interactions and infrastructure.
