1. A method comprising:
controlling, through a telecommunication network, a first time base, of a first timing device at a first site, and a second time base, of a second timing device at a second site, to synchronize based on at least one of global positioning system (GPS) signals, a network time protocol (NTP), and a precision time protocol (PTP),
determining a maximum transmission time based on measuring a first signal transmission time, over the telecommunication network from the first time base to a start coordinator device, and based on measuring a second signal transmission time over the telecommunication network from the second time base to the start coordinator device;
determining a start time of the competition;
determining, after determining the start time of the competition, a time at which to indicate a start of the competition based on the maximum transmission time; and
controlling, through the telecommunication network and from the start coordinator device, a first display at the first site and a second display at the second site to indicate the start of the competition at the time.
