INDIANAPOLIS (WISH) — The month of May begins with “the greatest spectacle in running.”

Runners from all over gear up for the 500 Festival Mini-Marathon, with the first race starting at 7:35 a.m. Saturday.

At the Indiana Convention Center on Friday, participants were prepping. They picked out shoes and running gear, and checked out the course map. Organizers estimated over 20,000 runners for the big race day. There’s the 5K run and, of course, the half-marathon that runs through Indianapolis Motor Speedway.

This year marks the 50th annual Mini-Marathon. Organizer Linday Labas of the 500 Festival said, “We have five Indy alumni who have done this race all 50 years, so they just keep coming back. They like the other part of the month of May, celebrating and tackling it. I know it looks different now than it was 50 years ago, but they keep coming back, because they love the celebration around Indy Mini.”

Cecilio Martinez has marathon tattoos for all the times he’s run. He ran the Chicago, Berlin, Honolulu and New York City marathons. But, he only has one half-marathon inked on his calf, and that’s Indy’s Mini-Marathon with the 50th anniversary medal. He said this isn’t the first time he’s run the Indy Mini. “I like the course. I like the people. I love Indy Mini.”

Runner Karina McDougle said, “Unlike 2025, the race is going to be chilly with temperatures as low as 39 degrees. “Honestly, because I’ve been running in so much cold weather, I’m pretty used to that, and I would prefer that. I do overheat a lot. It’s great for me, I’m looking for a cool day.”

There are also lots of first-timers running the half-marathon, including Wabash Middle-High School wrestler James Day. “We’re just excited about the experience. They actually talked me into it. I didn’t want to do it originally. I ran one day this week. We’ll see how this goes. I just came back from a wrestling season, though, so I should be in a decent shape.”

At the end of the 13.1 miles, runners will receive a golden medal to mark their accomplishment.

Editor’s note: This story is part of the Monitor’s summerlong series following old U.S. Route 66 from Chicago to Santa Monica, California.

Just a few blocks from the Old Joliet Prison, Johnny Williams is standing outside a tire shop, waiting for a repair.

He’s a lifelong resident of the Joliet area, a father of six and grandfather of 10, and he remembers back in the day when the prison was part of the economic engine that made Joliet run.

“I remember when people used to sit out there visiting their people — on the buses, you know?” Mr. Williams says. “I have plenty of people whose parents and uncles worked there.” He gestures toward the 25-foot limestone walls, still topped with razor wire. “And as a child, I would always wonder — what’s behind that wall?”

So, he still marvels at how the once imposing former state penitentiary has been transformed over the past decade. Today, the people walking through its front gate are not prisoners or staff, but tourists and Americana-lovers there to have fun and celebrate the centennial of Route 66. The iconic roadway, noted in hundreds of anthems about America, passed right by the prison until 1940, when it was rerouted a few blocks away.

The prison once housed such infamous criminals as Richard Speck, James Earl Ray, and John Wayne Gacy. But since its closing in 2002, it has become a site for concerts, film viewings, and today, an event dubbed “The Big House Ballgame.”
