From 20 to 40 years of age, Gary Koutsoubos gave up on running. The former high school and junior college runner had put that era of his life in the past. Instead, he opted for a sedentary lifestyle that left him overweight and unhealthy. After turning 40, Gary decided that enough was enough. Now at 48 years old, Gary is one of the best 45-49 year old marathoners in the country. It is a remarkable turnaround and a story that continues to grow. Next month Gary will be running the Boston Marathon and aiming to break his 2:55 PR and possibly go under 2:50! You can follow Gary at www.instagram.com/garyisarunner.
