Run Cannonball Run Shorts
You might want to just wear a bathing suit.
They're $88, which is pretty expensive for a pair of shorts. If running and swimming is part of your regular routine, then you might be able to justify it. But for those looking for a solid pair of running shorts, you should consider Tracksmith's Van Cordlandt Shorts, which are cheaper (and happen to be Rebecca's personal favorite). Or at the very least, consider some workout underwear that you can count on drying fast.
