Since his first marathon in Rome in 1996, Kritartha has run 14 other marathons, a couple of 6 and 12-hour races and a 100 km race. He has been actively organising World Harmony Runs in the Czech Republic since 1995.

In 2006, with a few of his friends, he set up the first visit of the World Harmony Run to Morocco. Since that time it has been organised every year on a regular basis. He says, "it was a unique and fantastic experience for me visiting such a different country and I am therefore very much looking forward to this year's Australian running adventure."
