Registration for the 37th Marine Corps Marathon begins online at 3 p.m.

Although registration will not be available at the roadshow, there will be giveaways and entertainment outside the Rosslyn Metro station, the marathon’s Web site said.

The marathon’s course winds along the Potomac River, through parts of northern Virginia and D.C.

Last year, the marathon’s 30,000 spots sold out in 28 hours, according to a press release.

This year’s race will be held on Sunday, Oct. 28.
