"From the very first day, I wanted to do the parkrun. I love running and the only time I get to run is on a treadmill in the gym. Then I got the chance to run around the prison every Saturday and I jumped at the opportunity." Mick has made quick progress, achieving a parkrun personal best of 18:25, which he hopes to drop to 18 minutes by the end of the summer. He is very focused on his training, which he undertakes twice a day.
"I do the treadmill four times per week and I do weights every day. I do weights in the morning from 10am-11.45am and then, in the evening, I come down to the gym at about 5.30pm and run until about 6.15pm.
"I love running, I don't know what it does [to me]. I used to take drugs but I don't anymore. I am off drugs two years now. I get a better buzz from running and training and I feel better now than I ever did with drugs.
"I love going to the gym and training all the time, I like the people I meet here. As a young fella, I didn't see the benefits. Now that I put my mind to certain things, I see the rewards from it. I get up fresh. I go asleep earlier. I eat well."
This life is a million miles away from the one which resulted in his drug addiction, his crime and his incarceration.
"I was taking drugs out there, I got involved in a lot of crime and I am in here for a murder. I am in here 11 years. I don't know how long I have left."
Does he think that parkrun can break down barriers and promote integration into the community for people in his situation?
"Definitely. Even when the visitors come in to run with us, they have a chat with us after. There is a parkrun in my local area at home and my brother is starting to do it now. He is training for it and I am hoping that maybe he can come in here and do it with me one day. I will definitely continue this when I get out."
When asked if he understood why people on the outside might criticise the Progression parkrun, he says: "I know what you mean. I did do wrong out there, but I am after changing my whole life for the better. And I am a better person today than I was 11 years ago. I have engaged with all the services in here, and I am positive about things."
