Distance running is a fast growing sport with wide appeal. Many now seek a new challenge, beyond the marathon. Ultrarunning offers that new challenge. The original booklets on Ultra training edited by Andy Milroy featured articles from experienced elite performers. They sold thousands of copies before finally going out of print. The Road Runners Club, long committed to promoting the sport, agreed to combine material from the various booklets plus new material in a new updated book. The advice in the book, from the rich vein of experience, varies enormously. No two runners are alike. Runners should take those elements which best suit them from the articles.
