Locals, look out! It’s time, once again, for the popular marathon. This year’s event also includes a half marathon, 5k, and family fun run. Begun in 1998, the annual marathon takes place on the first weekend in March. The starting line will be on Robert Grissom Parkway, just south of the intersection of Grissom Parkway and Monticello Drive. It will wrap up at the Pelicans ballpark, and of course there will be desirable race swag. Local drivers: expect congestion between 4 a.m. and 2:30 p.m. along the race route and allow lots of extra time to get to your destination. Robert Grissom Pkwy./Monticello Drive. Saturday, 7 a.m. $25-$134. (843) 918-1000, www.capstoneraces.com/myrtle-beach-marathon/
