Running skirts aren't exactly new -- we've covered them here at That's Fit on a few occasions. However, they're definitely gaining in popularity, so I figure it's a topic well worth revisiting. In fact, Runner's World had an article earlier this summer about the rise of running skirts, citing the fact that there is now a series of SkirtChaser 5K races (warning -- automatic sound at this link). And if the fact that there are now races based on the popularity of running skirts doesn't convince you that they're big right now, then I don't know what to tell you.

So what's the benefit of wearing a running skirt? Well, for one thing, it provides the comfort of spandex running or compression shorts without the worry of how your tush looks, because the skirt covers your bum in a much looser fit. Many of the skirts come with long shorts (seven inches or so), or even with full tights. Or, of course, you could always wear your favorite fitted shorts underneath.

Second, lots of them offer pockets, which to me is a huge bonus. I often run my long distances alone, and it's a pain to have to carry water, a phone, keys, and an iPod.

Third, they look cute. Scoff if you want, but there's nothing wrong with looking good when you work out. I'm not telling anyone to do her hair or makeup before hitting the gym -- I don't even think you need to match if you don't want to. But, I love the idea of wearing something to a workout that doesn't look ridiculous if I'm running errands afterward.

Plus, since it's not super-fitted, there's no embarrassing butt sweat. You know what I'm talking about.

So where can you find the right running skirt for you? They're sold all over the place now, but I've listed a few of my favorites in the gallery. And, if you've already found one you love, leave a comment and tell me all about it!
