Free Chapters


The available free chapters are mostly excerpts taken from the books.  In some cases, such as the lengthier chapters on the 2011 and 2013 Yukon race, these are included as full chapters, as they may be included in future editions of the published books (and it would not be fair to expect people to buy two copies of the same thing).

If you enjoy these excerpts it is hoped you will feel inclined to buy the main books from which they were derived.  Doing so will enable me to do more of this sort of thing, write about this sort of thing, and in so doing hopefully encourage others to improve their lives for the better.  If you have no intention of altering your life in any way whatsoever, you might at least like to enjoy a few moments of living vicariously through my adventures.  I mean, they're not bad as far as adventures go, and with your support they shall become ever more grand and outrageously dangerous.  Thank you for your support, Mark.
