As youngsters, we tricked out our tricycles with fuzzy pompoms and decked ourselves out like superheroes for after-school cruises through the neighborhood. This Saturday, the Tour de Fat resuscitates our inner kindergartners with a daylong tribute to bikes. The two-wheeled tomfoolery begins with a costumed parade through Golden Gate Park, followed by a contest featuring such wacky categories as Best Rider's Costume and Most Original Mutant Bike. The goings-on also include Devotchka's warped Eastern European-inspired carnival music, nerd par excellence Pete Sweet, and the Yard Dogs Road Show.
Come in costume -- or be heckled -- for the parade at 11 a.m. (the festival begins at noon) in Golden Gate Park's Speedway Meadow, JFK & 28th Avenue, S.F. Admission is free; visit www.sfbike.org. -- Jane Tunks
Runner's World magazine recently named San Francisco the best running city in America, citing the "unscripted adventure" of daily runs and comparing the prime conditions for jogging to surfing on Oahu's North Shore. It also revealed something we didn't know: The Golden Gate Bridge will be open to racers in the San Francisco Marathon, an event now presented by the magazine. Up to 15,000 runners are expected to compete in the day's races, which include a marathon, two half-marathons, and a 5K run. The gun fires at 5:20 a.m. at the corner of Embarcadero and Mission streets, S.F. Registration is $30-91; visit www.runsfm.com. -- Michael Leaverton
Day's Catch Praise the salmon
Wild salmon season first opens far north at the Copper River, a big, fast, freezing glacier-fed river that dumps into the Gulf of Alaska. It's a bitch of a place, causing the fish to pack on extra fat and oil for their yearly rounds, which makes them flat-out delicious. Of course, all Pacific wild salmon is worthy of praise (as opposed to that farmed excuse), and that's exactly the plan at the Ferry Building's "Return of the Salmon: A Seasonal Celebration."Stores will pull out their salmon wares, chef Chad Callahan will demonstrate cooking techniques, and there'll be a raft of fish-related events. Sunday's Salmon Roast Lunch should be the highlight, which is a steal at $15 a plate. (Remember, you're in San Francisco.) The celebration starts at 8 a.m. Saturday at the Ferry Building, Market & Embarcadero, S.F. Admission is free-$15; visit www.ferrybuildingmarketplace.com. -- Michael Leaverton
