What a grueling day for us monitoring Don, it must be a real hell for him. It took forever for him to get to Way Point 4 (8 hours). And within one hour he had made it to Stage 5.
The team are anxiously awaiting him at the bivouac, but they know no more than we do. They suspect he is just taking it slow and steady. Also, the trucks will now be passing him, to add to the stress of the day.
They think it will be two more hours before he will make it to the end. Whew!
