Nicknamed the “Alien Half” thanks to its nighttime running and the glow-in-the-dark gear organizers plan to hand out before the start, Roswell’s Area 13.1 Half Marathon is set to make its 11th annual running during an early-evening run with plenty of shade, through one of the metro Atlanta area’s most popular parks. The race is set to take runners through portions of the Chattahoochee River National Recreation Area and Morgan Falls Reservoir, along a combination of park trails and roadways that run alongside the Chattahoochee, which flows into and through nearby Atlanta from this smaller suburb that’s home to some 88,000 residents of its own. Organized by the locally-based running store chain Big Peach Running Company, the race is scheduled just as the sun is going down and the possibilities for an “alien invasion” are on the rise.
