GPS Tracking

Do any of you out there know if the timing chips we wear are GPS trackers or do they only track us by the times that we cross the  5 k markers? Many thanks


  • In London ? No they're not GPS - but they will register every 5k and the half way point.
  • Thanks a lot cougie, I did think that was how it worked last time but have heard talk that you can be tracked on google type map, thought this was a bit optamistic
