The second annual Christie Clinic Illinois Marathon will undergo changes this year as coordinators look to reroute traffic and increase supplies for participants.

There are about 5,000 more runners participating in this year’s marathon, said Marsha Osterbur, media coordinator for the event. She said despite the increase in runners, the number of volunteers – about 2,500 people registered – is about the same as last year,

“We are very fortunate they all came out,” Osterbur said.

Because of the increased number of participants, more supplies will be required, she said.

There will be 12,000 gallons of water, 1,200 safety cones, 140 portable toilets and 400 trash bags, she said.

Police officers will be at the 54 intersections with the heaviest traffic areas, and volunteers will cover 321 intersections in quiet neighborhoods.

Illini Radio Group will be at the race for three hours to advise people about traffic conditions, and a police officer will monitor the marathon by helicopter, Osterbur said.

Some businesses may face a decrease in customers since roads will be blocked off for the race. Great Clips on South Lincoln Avenue will open at 9 a.m., its usual time, but may be affected since the avenue will be closed off.

“We’re going to be open. Depending on how business goes, we might close early,” said Taryn Wilson, assistant manager at Great Clips. “We’re hoping it will pick up in the afternoon.”

Osterbur said since the race starts early, the roads should be clear by the afternoon.

“If people do their errands at 1 (p.m.) or noon, it shouldn’t be a problem,” Osterbur said.

Bus routes will also be affected by the race, as every bus route will have a reroute, said Jan Kijowski, marketing director for Champaign-Urbana Mass Transit District, or CUMTD.

“The bulk of inconvenience will be in the morning,” Kijowski said.

Details of reroutes are on the CUMTD website and the regular bus schedules will be reinstated as soon the roads are cleared, she said. She advised people to allow extra time for their activities due to delays.

The route of the race will differ and be “less disruptive than last year,” Kijowski said. Downtown Champaign will be much less congested, she added.

Unlike last year, every runner who finishes a race will be awarded a medal, Osterbur said. She said they are adding the 27th-Mile Celebrate Victory Bash, which will be held at the intersection of First and Oak streets from 11 a.m. to 6 p.m. with bands, food, a NASCAR simulator and kids’ games.

“It’s going to be like a festival,” Osterbur said.
