Has anyone tried using Garmin Connect w/ Live Track for the race? I know coverage is spotty, but it might be enough to provide SOME live info to spectators. A few of the Garmin watches, my Fenix 3 included, will connect to a smartphone via Bluetooth and then provide literal live tracking to anyone with the right link (the Connect app emails a link to those you choose as soon as you start the live track session). I've used it in a few half marathons and it seems to work well without being a huge drain on the phone battery (my iPhone 6 still had 90% battery after a ~1:40 half). I'm planning to give it a shot this year. I assume the updates will be "lumpy," as the phone will probably hold position updates until it has signal, then dump them all at once, then hold again until it has signal again, and so on/so forth. But, it should give your "fans" a good idea of where you are (or were) at any given time.
