If we identify which states he has not been to yet, we should be able to narrow down his next target. Then someone could follow him at a race and ensure that he runs the whole course, as was done at the Maine half marathon, where he was suddenly unable to run his usual marathon pace for half the distance.
yes. he was followed and he ran a legit 1:28 for maine half marathon. seems slow considering he "ran" 2:49 chip time at vermont city, 2:49 chip time at missoula, and low 2:50s chip time at a bunch of other places.
