I'm not sure exactly when they stopped, but I'm guessing that it was sometime between 3:30 and 4:00 am Illinois time since I woke for a few minutes around then, checked the Tractalis app on my iPad and saw that #509 wasn't moving. When I got up around 6:00 am, I kept checking it, and -- funny thing! -- around 7:30 am, while I was getting dressed to go to work, I noticed that the tracker moved one-tenth of a mile. I imagined Keith stumbling toward his bike in a hotel parking lot, and lo and behold, two minutes later when Tractalis refreshed the data, #509 was moving at 11 mph. A few minutes later, Keith made an official check-in at the Mexican Hat, UT time station (#12 - checkin at 8:34 RAAM time.)
He checked in at time station #13 (Montezuma Creek, UT -11:18 RAAM check-in time) and was crossed the border into Colorado around noon Illinois time (13:00 RAAM time.) Shortly after that, the icon for tracker #509 disappeared from the map, and there was no more data for about two hours. But I and others noticed that the trackers for other racers were also disappearing at about the same location, and I received a text message from Lisa saying that they were having real difficulty getting a cell phone signal. I checked the map, and it appeared that Keith was moving through a canyon just west of Cortez, CO (McElmo Canyon.)
Pretty soon, his tracker number reappeared near Cortez and he checked in at time station #14 there at 14:44 RAAM time. The tracker stayed near Cortez for a while, so I'm guessing that was a planned rest since his check-in at time station #14 in Durango, CO, showed that his average speed had dropped to 9.71 mph.
