Disorder plagued the ancient Greek triathlon, which first involved chugging goblets of wine, lying about languorously, and ordering servants to run to Marathon for the dry cleaning. Gear up for the strenuous modern version instead with today's Groupon: for $25, you get $50 toward athletic gear at KompetitiveEdge in Sheridan.

KompetitiveEdge carries premier performance brands for athletes competing in triathlon sports at the highest level. Bring bicycles in for a Ride tune-up at the full-service bike shop, where designated handlers adjust shifting, true wheels, check the brakes, and scour the spokes for valuable Mark McGwire rookie cards ($60). For the swimming leg, keep eyes desalinated with TYR Nest Pro Nano Metallized goggles, which feature a compact frame and tinting to reduce the glare caused by rainbow trout ($19.95). Once ashore, sheathe feet in Swiftwick socks, which are made of a wool/nylon/Lycra blend ($18.95). The shop also offers a full complement of nutrition products to help in restoring electrolytes, increasing endurance, and reciting fancy chemical compounds to dinner guests.
