So the more we dig into this the more we seem to agree that there is no way of proving via GPS that one did a legit transcon?
Nobody ever said that you can prove a Trans Con record attempt ever.
You always have to believe the runner what he said he did.
If the runner has a good running record it might be believable.
A good example is Al Howies Trans Canada record around 64 miles/day in 1991. He was a great multiday runner with great results.
That's why we run real races because they produce: records.
