Query: Watch the editions!!!

Just a note to those that are interested in buying this book. The 13-week run/walk program was completely revised between the 2001 and 2005 editions of the book. The 2001 edition is a much gentler approach, while the 2005 edition assumes that you have a certain level of fitness. Just to illustrate: the very first session of the first week of the 13 week program in the 2005 edition calls for "run 1 minute, walk 2 minutes; do this 12 times" (the 9th time just about killed me), whereas the 2001 edition of the book starts with "run 30 seconds, walk 4 minutes 30 seconds; do this 7 times". So if you're more fit you may be happy with the 2005 edition, otherwise try to find the 2001 or 1999 editions of the book. Otherwise, I liked the book a lot.
