If you'll be in and around downtown Princeton on Sunday, you'll want to pay attention as many roads will be closed to motor vehicle traffic for the HiTops Princeton Half Marathon.

The marathon, which winds its way across most of Princeton, is expected to use the same course as last year, officials say.

The race starts on Paul Robeson Place, which police say will be closed to traffic starting at 5 am. Click here to view the racecourse on a map.

Intersections along the course will be opened as quickly possible after runners pass through, however, motorists are asked to allow for extra time if you're driving through town between 7 and 10 am on Sunday.  This map also shows the times that runners are expected to passing various locations.

Redding Circle residents, meanwhile, are asked to walk down to the intersection of Mount Lucas/Ewing Street to access New Jersey Transit buses between 7 and 10 am on Sunday.

You can still help HiTops with their fundraising efforts during Sunday's race, of course, and if you're free come out to cheer on the runners as they take on the 13.1-mile course. Click here for more information about HiTops and the marathon.
