Run Forever (2018) Amby Burfoot

This is basically a "how to run" book written by a former marathoner and former editor of Runner's World.  He's very good practical suggestions that boil down to: don't get discouraged; count the minutes but don't look at the clock; don't worry about your speed; think long term.  The reason I have a minutes chart now is because of him.   This is a good read.
