A 39-year-old dad of two, Harold Cabrera is your typical sports weekend warrior, who decides to complete three big challenges before turning 40.

Harold Cabrera was born in the Philippines, grew up in Winnipeg, Canada and lives in London, England. He works as a Software Developer and Data Scientist for Wise Traders where he develops stock trading systems. He spends most of his time with his family, plus running, cycling and swimming. Harold has co-authored and published C# for Java Programmers (Syngress Publishing, 2002).

Harold says, “After signing up to do the Paris Marathon and the Outlaw Triathlon (which was my first Ironman Distance triathlon), and planning to climb Mount Kilimanjaro in the year leading up to my 40th birthday, I asked the question if this was some sort of midlife crisis. And that's when I came up with the idea of chronicling my journey of trying to complete these challenges and turning this into a book.”
