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.
