I don't understand why he would have done this. Surely travelling at 60 mph would be obvious on his GPS? Even Guinness would want to understand why he is doing miles in a minute.
What you are saying ties up, but surely he couldn't hope to get away with this? I understand him being in the back of a vehicle and it going at 7 mph (it sounds ridiculous), he could hope to get away with that.
This is a fair point. I think both cases are somewhat far-fetched -- that he ran unassisted through the Mohave back country for 4 hours on a 95 degree day (temps were probably 75-90 as he ran before noon) or that he got a ride at highway speeds and then had to fudge the GPS. Everywhere else the RV was going running speeds. Why screw that up on the first state with a runner in the vehicle?
It would be really helpful to have more info of that truncated segment, even a screenshot for the time being. Just kind of coincidental that's the one that's cut off.
