Shertenlieb said her husband convinced her to come home, get warm, have a nice meal and then, if she was up for it, to go back out together after the rain.
Around 8:30 p.m. they took a cab to the spot where Shertenlieb had to stop earlier in the day and finished the nearly 11 remaining miles of the course together, and where greeted at the finish line by cheering family and friends.
“Oh my goodness, that was crazy,” Shertenlieb said. “You can do anything. It may not be how you imagined it playing out, but you can still get it done.”
