Running on a treadmill is extremely boring. Weight lifting is fun.
Running barefoot outside---if you can either find a good place for it or the courage to declare your current place good enough, is a thing of joy.
(My current home, London, basically has temperate weather all year round. It doesn't really get cold here.)
When I left my job and was gymless for a short period, I started running along the water in San Francisco after not having run for several years. Within two weeks, I was doing about ten miles. It's really hard to overestimate how much easier and more pleasant beautiful surroundings make walking and running. (Temperate weather 365 days a year doesn't hurt either).
