" might put it off and run when they got there, but contrary to popular opinion, beach running is only jolly fun for the first five miles or so. After that, the cute little waves become redundant, the sand reflects the sun up into the eyes blindingly, grains of sand slip annoyingly into the heel of the shoe or flip up on the back of the leg. Fifteen hot miles on a long, flat beach sounds like good sport only to those who haven’t actually done it. Also, the ocean is too infinite; the run seems as if it will never end. "
