Rainer Klaus: 18 days, one hour and 26 minutes

From the GDR blog:

Rainer Klaus called from Antelope Wells at 1:26 p.m. Tuesday for a finishing time of 18 days, one hour and 26 minutes. He enjoyed the morning's ride and said he stayed ahead of the rain. "It was a very easy stage today," he said. "Had I known the stage was so easy, perhaps I would have gotten up earlier in the morning, so that would have caused a below-18-day finish. But I'm very happy to have done it. I'm healthy and I'm feeling well mentally and physically." He said he would call back in with more details later.
