I predict that Rob suffers through 40mi days until Laz has run out of funds to follow, and claims that he gave it his all but ran out of energy from the cumulative effect of the 75mpd he was doing the first 3 weeks.
Because if he quit now he'd basically be admitting to it.
Nice, and here's a sick angle that may well happen. Rob barely waddles to the finish line missing the record by a huge margin. He sells this "witch hunt" as compounding to his already difficult upbringing and rough life. This gives him an excuse for having failed and he gains many more fans with sympathy points.
