CHAMPAIGN, Ill. (WCIA) — There was a sea of orange and blue Sunday morning in Urbana.

It’s officially Homecoming Week at the University of Illinois. It all kicked off at the Alice Campbell Alumni Center with a record breaking 400 runners participating in the Homecoming 5K.

The U of I Alumni Association President said that it’s not just the fun events and the big game making U of I’s Homecoming so special, though.

“The myth or lore has it that Illinois has the longest, continuous Homecoming in the country. So, we have been around as the Alumni Association for right around 150 years. I don’t know that Homecoming dates back quite that far, but we have the longest, continuous Homecoming in the country. We’re incredibly proud of that, and I know that it’s a pride point for many of our alumni, students, and faculty here at Illinois,” Dave Bambrey said.

The 5K isn’t the only event planned for the jam-packed week. Bambrey said that he is looking forward to the Alumni Awards Gala on Thursday, the parade on Friday night, and the post parade party open to the community.

And of course, Homecoming Week culminates on Saturday when the Illini play in a sold-out stadium against USC at 11 a.m.
