My wife, Shelia Allen is in training to run the Mohican Trail 100-mile race June 16-17 near Loudonville, Ohio. Yes, I said 100 miles. On foot. With a 32-hour time limit. The terrain is hilly, with treacherous footing chock full of roots and rocks. I am planning to pace her through the last 40 miles. How does one get ready to cover 100 miles on foot in a little over a day?
