When legendary Canadian marathon runner, Martin Parnell, had a life threatening blood clot he was inspired to recover and run again when he read about the first courageous Afghan woman to participate in a marathon in her own country, Zainab. He invited young filmmaker and Ryerson University graduate, Kate McKenzie, to join him in documenting the journey and trained her to run her first marathon. The result of this journey is the documentary "The Secret Marathon" which will be released this year.
