Face the facts, cyclist dude. It's not just the oxygen bath from the cardio workout conferring that superhuman glow. It's ego too. Your butt may feel like it should be severed from your body and sent to a spa for a three-day cure, but you did it, baby! Forty miles roundtrip! Not bad. Bragging rights are a definite benefit of this pier-to-pier ride along the southern end of Florida's ritziest sandbar. Still, talking length of ride and arrival time with the pedate and prone back home is easy. The deeper pleasure is something you carry inside, something hard to put into words, a kind of imprinting that happens as you cruise under the green gothic spires of gigantic Australian pines, find your nostrils overcome by the inexplicable smell of lavender, glimpse the Atlantic Ocean from the bridge by South Inlet Park. In the tiny town of Briny Breezes, you can contemplate Florida's vacation past in cement cottages that have yet to face the wrecking ball or gawk at who-the-hell-has-the-money-to-afford-these mansions lining A1A. Bike paths appear and disappear, but there is a sidewalk for a long stretch of the ride. You can park your car at Deerfield Pier for $3 a day. And hey, the Lake Worth Pier is worth a stroll before you head back south, so stretch out those overworked thighs and calves, baby.
