Spring is here and it's time for the ‘Emerald Across the Bay 12K run or walk. Always the third Sunday in March- in 2009 the date is March 15th. More than 5,000 runners and walkers, many of them veterans of the scenic, route from Sausalito to San Francisco across the Golden Gate Bridge, will participate. The starting line at East Fort Baker looks across the Bay at a magnificent view of the city of San Francisco. As the run progresses across the Golden Gate Bridge on the west walkway, down into the Presidio, along Crissy Field and Marina Green and into Aquatic Park on Fisherman’s Wharf, runners experience one inspiring panoramic view after another. Emerald Snacks is proud to be returning for the fifth year as the title sponsor. The Emerald Across The Bay 12K ‘world class’ post-race party is such a highlight to the run it has its own name, "A Celebration of Running." And, it's the kids from the Edgewood Center for Children and Families, the long-term beneficiary of ‘Emerald Across The Bay 12K’, who celebrate the most at the finish line.
