very interesting! As someone else noted, the tracks for RY on foot are very wobbly, and stick to the side of the road; whereas RY running 6-minute miles is very smooth and often right down the center. Smooth is probably to be expected but it's easy to pick out when you're looking for it. And yes, there's that button hook at the transitions between the wobbly and the straight lines. It's fairly easy to put together a story here. For example:
Look at mile 2.5 to 4, leaving Flagstaff, AZ, it looks like he is on foot (wobbly line), then at mile 3.0 he gets in the RV. They are still in the Flagstaff urban area, and they get a quarter of a mile, stop, then RY walks around the vehicle, gets back in, goes another half mile to 3.6, and comes up to a Cocono Travel Center (Google Streetview:

I tried to screencap the different sections above. Probably hard to follow since they are in a different order, but hopefully it makes sense. I did a mouseover on the part of the run (bottom) that shows the pace in context with the rest of the run. When you mouseover a location in the graph on the bottom, a blue dot shows in the map view where that pace was being recorded.
