I am sure the ultra guys are good people. But. Their sole task is to keep an eye on RY. According to this latest account, when they went back to find Rob they were informed that he had stopped for a massage. A massage takes a good chunk of time. How long is he actually out of their view to do God only knows what?
According to the post it was he was out of there sight for 1:14 (or at least the segment took that long), but they were only 2.5 miles up the road (or the entire segment as that long). It's such a small distance I highly doubt he would risk getting caught red-handed now for such a marginal gain.
