As the largest AIDS fundraiser in the Southeast, AIDS WALK ATLANTA has raised millions in an effort to find a cure for AIDS. Now in its 19th year, the walk and 5K run contribute funds to restore the health of those combating the disease. AIDS Walk Atlanta raised nearly $900,000 in 2008, and has set an even higher goal of $1 million for this year. What could be a worthier cause, complete with a little exercise? Run, 1:45 p.m.; walk, 2 p.m. Piedmont Park, 1071 Piedmont Ave. 404-876-9255. www.aidswalkatlanta.com.
