I used to love running. As a teenager, I would go for runs routinely. I wasn't part of a team and didn't compete. Running gave me a joy. It offered a strong sense of pushing myself. Generally that meant for speed rather than distance. I would run for an hour or so through the woods near home and try to improve my time for a given route.
I wasn't religious about running. Sometimes I'd take off extended periods and frequently I wouldn't run at all during the winter months. I never really enjoyed the cold air burning in my lungs.
