Choosing where to post
If you have a question, start in r/beginnerrunning: it is set up for exactly that, and with about 52 new posts a day there are plenty of people around to answer. Jokes and memes have their own homes in r/RunningCirclejerk and r/runningmemes; the serious communities tend to remove them, so keep the two apart.
Before posting, sort a subreddit by “Top” for the past month: it shows in a minute what that community rewards. Always read the rules in the sidebar first — each community is run by its own volunteer moderators. Our guide to searching Reddit explains how to dig through any of these communities, and the subreddit info tool gives you the stats of one we don't list.
