In this spiritual memoir, Joshua Rice explores the spaces of middle age through the lenses of the Bible, long-distance running, and modern psychology. Our larger-than-life companion is Abraham and his rabbinic interpreters--beloved as no other in the Jewish tradition. Always on the move, always in-between, never quite arriving, the great patriarch of Genesis creates space for making peace with the past, for pushing new limits, and for sprinting headlong into the second half of life.
