Seeing that i wrote said book, i feel i should put up some defence.
The publishing process is complex and text is played about with by editors, typesetters etc, so unfortunately mistakes do happen.
It is amazing to think that despite myself reading it through dozens of times, as well as professional proof readers and my editors, that mistakes slip through the net and end up in the final version.
All that said and trying to shift the blame, i am not claiming the book is a piece of literary genius? Far from it. It was my first book and i wrote it in my capacity as a personal trainer, experienced in training a range of mixed ability runners how to run HM and M's, not as an authority on the grammatical or written aspect of the English language. I should have editors to pick up on my grammatical shortfalls, but maybe they were having an off day when editing and proof reading the book.
RE the title - that was 100% the publishers choice of book title, as was the cover design and back page blurb! I'll take my share of the blame for the other 50,000 words, but not the covers.
My apologies if the grammatical errors in the book have made you lose confidence in it to help with your training, but hopefully you'll be able to look passed the erors (i couldn't resist it) and use the content to help you achieve your marathon goal.
Good Luck.
PS, Try a 5 mile fartlek session rather than a 5 minute one (this mistake was the first i noticed and will be amended in subsequent editions)
