Re: the debate over Strava "moving time" vs. "elapsed time", these data show that when he was moving, he was at many times "running" at ~ 6:00/mile pace, in very difficult conditions.
Right? Or am I misunderstanding?
Correct. The thing is, he could be running .1 miles at a time, taking a 30s break, going again, etc. Still too fast, and stupid. But we can't know anything about actual elapsed time over a certain mile or something from this Strava.
As some have mentioned, you could cross-reference to the RV tracker for some more info.
The Strava "best efforts" will be accurate - actual elapsed time for that distance.
