Have you ever considered running a marathon? Or, if you have run one or more marathons but are not happy with your time or the experience, this is the book for you. Ron Berby has run 221 races of marathon or farther, 62 of those 50 miles or more, and 19 of those 100 miles or more. Of the 159 marathons he has run, 55 of them were in under three hours. Ron’s experiences in running long races between 1974 and 2001 have made him see two factors as necessary to run a marathon with strength at the end, and for the runner to look forward to the next one. 1) Sufficient mileage and 2) The ability to delay gratification.
