Tom Dinwoodie will be the first to admit that he is something of a Jack Quinn's Running Club rehab patient.
A little over two years ago, he was anything but a runner.
"I was smoked about two packs worth of filterless, roll-your-own cigarettes for 20 years," Dinwoodie said.
In May, 2010, his co-worker at Honeywell, Karen Barry confronted him about his nicotine habit.
"She said, why don't you put those nasty things down and start running," Dinwoodie said.
Barry was a runner at the Jack Quinn's Running Club. Dinwoodie gave it a try. It wasn't easy at first. And quitting smoking was tough.
I ran the Hellacious Trail Challenge in (June) 2010," he said. "That morning I had two cups of coffee and smoked two cigarettes for breakfast. My goal was to just survive the race (about nine miles on tough trails). I finished in an 1 hour, 55 minutes."
In two years, he has given up cigarettes, finished four marathons and is training for the Run Rabbit Run 50-mile endurance race in Steamboat Springs.
"That's what running does for you, now I'm really insane," he said.
Dinwoodie reached a big milestone at the Jack Quinn's Running Club on Tuesday, completing his 100th trip around the 5K course.
"This community, these people are awesome," he said, looking at a standing-room-only crowd at Jack Quinns.
Dinwoodie earned his black 100-run club shirt on a night for longtime Quinn's runners.
Jeff Lindemann became the 15th runner to complete 200 runs.
About 53 runners earned their 10-run shirts.
