To my knowledge the 10K Challenge began sometime near the beginning of this year (2012). It might have been January, however, I’m not certain on that. Regardless, I joined around March 16, 2012, and stopped working the program around June 2, 2012. Recently (this month or last month), the 10K challenge had a re-launch or maybe it was just a face-lift. All I understand is that some of the website looks different now, and the system was changed with how you can progress with it. However, I took about an hour and browsed the system and the majority of it looks the same as far as the training goes. Ok, adequate history, this is a 10K challenge review, and I’ll be providing my thoughts and viewpoints on this program.
