The 21-year-old New Orleans Red Dress Run is an adults-only event for regular "hashers," runners and revelers alike. The international network of Hash House Harrier chapters bill themselves as drinking clubs "with a running problem," and local hashers gather for weekly runs. As the New Orleans Red Dress Run has become more popular for its festive aspects — morning drinking, running in drag, outrageous fashion, hanging out at bars — it has grown to include thousands of participants and generate hundreds of thousands of dollars for local nonprofits. There now are two levels of participation: the open-registration Red Dress Run is a 2-mile jaunt through the French Quarter and Marigny on Saturday; the hasher members-only package also includes Friday night and Sunday morning runs. Registration for the Saturday run includes pre- and post-run parties in Louis Armstrong Park, beer, barbecue and music by Dash Rip Rock and The Breton Sound. Registration is available on www.nolareddress.com and in the park beginning at 7:30 a.m. Saturday. Advance registration is $70; $80 on the day of the event.
