The main thing with wind is the annoyance factor. It can be impossible to feel smooth and relaxed if the wind is too strong, even if you’re running with a tailwind. The common advice on windy days is to head out into the wind so that you’re not facing a headwind on the way home, because that could chill you. I think the opposite approach is better. I sort of trick myself into staying out for longer than I otherwise would on horribly windy days by heading out with the wind at my back. Once it’s time to turn around and head home, I’m x number of miles away and have no choice but to finish the job. (And by then I’ve warmed up.) I’m much more likely to get in a decent amount of mileage that way then willing myself through the opening miles into a headwind, when I’m not yet in a groove.
