Sunday's Rite Aid Cleveland Marathon, half marathon and 10K all start at 7 a.m. sharp, but the road closures will be in effect at least a half-hour before then. There's a seven hour course time limit so most of the roads are back open by 2 p.m.
The Shoreway, however, from West Boulevard to East 9th, will reopen at 4 p.m.
Marathon runners will go through parts of downtown Cleveland, Ohio City, Tremont, Lakewood and Rocky River.
Keep in mind, If you plan on cheering on the runners, you'll have to find parking on side streets.
Below is a course map of the full marathon and a list of more than 30 road closures and the start and end times.
