I know exactly what you mean about the weather in Seattle - I used to live near there for a few years (in Yelm) . My sister and her family live in Rainier. Anyway, after this 5K I'm planning on doing an 8K in the Spring, so in order to train for that I'll need to join a gym myself. It snows a lot in PA!
That's awesome that your husband has started doing this too! I've gotten a few friends back home in Missouri to do it as well.
