Event: The Fifth annual Marine Corps Marathon.

Time: Start is 9 a.m.

Starting and Finishing Line: Iwo Jima monumental in Arlington.

Where to Watch: The front window of Clyde's (or any other suitable watering hole) along M Steet in Georgetown between eight and nine miles is the place to be; the terrace of the Kennedy Center between nine and 10 miles will do in a pinch; the steps of the Capitol building offer view of runners as they make their way up and down the Mall; runners "hit the wall" at 20 miles along Hains Point and could use the company but East Potomac Park is closed to vehicles and you'll have to hoof it; from the foot of the 14th Street Bridge -- standing room only -- climb the stairs to the bridge and you can see the field head for home at the 23-mile mark, where last year's winner took the lead.

Parking: Available in the Pentagon North and South lots, with shuttle-bus service available to the start beginning at 6:30 a.m.

Radio: WMAL-630-AM.
