Building off of the success of the two previous editions of Run Fast , Hal Higdon will revise the third edition himself, providing consistency in voice, new information, and expertise from one of the most well known authorities in running. Run Fast , 3rd Edition will focus on how runners can improve their speed, regardless of their age, ability, or the distance. Higdon will inform readers how to maximize their potential without merely running faster. Training programs and tables will be expanded and revised to include up to date information. It will include more motivational and practical support for novice runners to broaden the audience appeal. The third edition includes new developments on running form, strategies for running longer distances faster, a new chapter on the importance of rest, how to knowledge for beginners entering their first race, and advice from the leading scientists and experts in the field. Higdon also includes his new 30/30 plan for beginners which involves walking and/or running for 30 minutes for 30 days. Higdon believes that once the 30/30 plan is completed, readers are ready to tackle a 5K.

The book also includes a modified and easier version called the 30/60 plan. Run Fast fits into a clearly defined place in the training spectrum, apart from marathon and half-marathon training books. This book is a steady seller on Rodale's list, and the new information will continue to bolster sales of this comprehensive and well-loved guide as well as to attract a new generation of runners.
