For what it's worth-
I recalled Karel using a different site/webpage on the PCT (and several Strava comments).
Running back through Peter's old site I see that he did use this service- though it went to a site he set up for the event (similar to this one but not a plug in).
The Strava was backup it seems and not a serious source of critical tracking. (I thought he tried to do the whole thing)
I also see a Stef chiming in on that effort as well who I strongly suspect is the very same Stef we are talking to now.
A skeptical backwoods bastard I may be... but all seems to check out.
So just sharing my homework with the class...
