Runners will take to the road Saturday for one of the Lowcountry’s most scenic races.

And those who are planning to run, walk or watch in the 21st annual Isle of Palms Connector Run and Walk for the Child are encouraged to arrive early. The Isle of Palms Connector will close to vehicles at 7 a.m.

Anyone arriving after that time can get to the starting line via Sullivan’s Island.

The race starts at 8 a.m.

About 1,100 people pre-registered, and race organizers expected an additional 300 to sign up Friday and Saturday. Last-minute registration begins at 6:30 a.m. Saturday at the Public Safety Building, 30 J.C. Long Blvd., Isle of Palms.

Weather is predicted to be about 68 degrees and clear at race time.

The run starts on Palm Boulevard and turns left onto the Isle of Palms Connector over the Intracoastal Waterway. Walkers and 5K runners will make a U-turn at a marked point on the bridge, while 10K runners will continue on to the entrance of Seaside Farms in Mount Pleasant, where they will turn around.

“The view is just amazing going over the Connector,” said Isle of Palms Recreation Director Norma Jean Page.

A post-race party will be held on J.C. Long Boulevard.

The connector will reopen after the last runner finishes, which should be by 10:30 a.m., “depending on how slow the slowest person is,” Page said.

The race benefits local organizations working to prevent child abuse and neglect.
