This book was been updated and revised, in May 2024.There are hundreds of books telling you how to run and how to train. This isn't one of then. This book is about the troubles that lurk on the trail. Ghosts, goblins, ancient gods, criminals, aliens, and creatures of the night waiting out there for the unwary to run straight to them. Lace up your shoes and watch where you step. Be careful out there.
