We entered it in the non-fiction category of the Publishing Innovation Awards this year and it was was one of three runner-ups for the Publishing Innovation Awards in the non-fiction ebook category, from among a lot of entrants. (There were separate categories for apps and multimedia enhanced ebooks.) It was awarded the QED (Quality-Excellence-Design) seal.
Here's what the judges said about Rick's work:
"Marathon: You Can Do It displays a creative design that does not distract from the text, making the pages visually appealing as well as informative. Tables contain a lot of structure, yet even rendered as art are easy to read. The 'Tips on Using This Book' for the iPad demonstrates a thoughtfulness and sensitivity to the reader's experience of this digital title."
