Weekend preparations for Sunday's marathon and half-marathon are underway.
Organizers are busy readying the Capital City for 12,500 runners to hit the streets. Traffic signs went up earlier this week to warn drivers of street closures and delays.
"The streets will be a little more crowded, we'll have a little more bike people out on the course, the paths will be a little more crowded," Race Director Nancy Sutton said.
The race kicks off at 7 a.m. at 14th and Vine streets, shutting down both lanes of 16th as runners head to South. Then, the course winds southeast to the bike path along Highway 2, and could become a problem to drivers trying to cross at 40th, 33rd or 27th streets.
"You may have to wait five or ten minutes," Sutton said.
20th Street from Highway 2 to Harrison and Harrison to 10th will also be completely closed. As half-marathoners finish up their route, don't plan on getting down 10th street in a hurry. A couple lanes will be shut down.
"That will probably be tied up until about 10 o clock, maybe even 10:30 in the morning," Sutton said.
Full marathon runners will then take Normal all the way out to Holmes Lake, closing eastbound lanes until about noon.
If you don't have a place to go, organizers are encouraging the public to cheer on the runners.
"They need that little pick-me-up and then there you are to make that noise and cheer them on until the end," Sutton said.
All other streets along the race routes will only be closed in the direction of the runners. To see the course map, click here.
