Any beach in our lovely, beach-rich county will do. Here are the advantages to beach running: You don't need fancy shoes?or any shoes at all; you get a better workout per minute while running in sand, which provides natural resistance, building more endurance/burning more calories per stride; the Pacific Ocean is seconds away from you when the heat gets unbearable; no !@#$%^&* cars; near-nude sunbathing humans everywhere you look (okay, this is often a mixed blessing); and if you're really cruising impressively, your odds of hooking up increase exponentially. The disadvantages? No shade; you may have to weave around several of your fellow beach bums; unpleasant aquatic aromas may waft into your nostrils; and whales have been known to wash ashore, which could really slow your pace. But overall, beach running rules, and we've got miles of the sandy stuff.
