The summer solstice conjures up images of Mother Earth types dancing around barefoot in Golden Gate Park. But for Bay Area sailors, the longest weekend days of the year are an excuse to “sail locally, celebrate globally” at the fifth annual Summer Sailstice. Organizer John Ardnt told us that the yearly event is the seafaring community’s way of encouraging landlubbers to get out on the water. Don’t have any friends with a sailboat? These sea dogs welcome gobs and greenhorns alike to become a part of their crews. On Saturday, poke your nose into Alameda’s half-dozen yacht clubs, which are having a joint open house, or navigate your way to Tiburon’s Paradise Cove Park for the South Beach Yacht Club’s blowout barbecue. Admission is free; visit www.summersailstice.com for information on specific events and to sign up for a boat.

Most people think they're pretty cool if they bike across town -- and they are, but it's nothing compared to biking 4,200 miles across the country. That's what six teenagers are doing on their summer vacation, and the Coast to Coast BikingX Launch sends the kids (including local 14-year-old Aryeh Canter) off in style. Even cooler, the ride is a fund-raiser for Camp Quality, a summer camp for kids with cancer. Join the bikers on their first mile or just cheer them on starting at 9 a.m. at Justin Herman Plaza, Market & Steuart, S.F. Admission is free; call (800) 654-5957 or visit www.bikingx.com.

In elementary school, relay races were our teachers' sneaky way of getting us to learn about cooperation, teamwork, and how to be a good sport whether we won or lost. Now the Presidio Relay is reviving this childhood tradition with its 20K race. Gather friends for a four-person team, in which each member hoofs it for five kilometers before passing on the baton to the next victim -- sorry, runner. Not looking forward to getting up early on a Sunday morning? There's a bright side: The course is mostly flat, and the money goes to benefit Hands on Bay Area. The sprint begins at 8 a.m. at the Presidio's Glass Palace, Building 924, Crissy Field, Halleck & Mason, S.F. Registration is $30-40 per person or $120-160 per team; visit www.presidiorelay.com.
