Mill Race Marathon, Half Marathon & 5K

Saturday, September 28, 2024 • Columbus, IN • Course Map

Columbus, Indiana may be a small town, but the Mill Race Marathon, Half Marathon & 5K is no small race, with over 3,000 finishers in all three races — and over 1700 in the half marathon alone.

The half marathon begins on Washington and 7th Streets in downtown Columbus and continues north briefly before making a turn left onto 11th Street and running alongside Mill Race Park for the first mile of the course. The half marathon continues by taking runners on a tour of Columbus, leading them past Garland Brook Cemetery, downtown Columbus, and small town residential neighborhoods near the town center.

The half marathon course is mostly flat with a few hills, particularly at the beginning of the course. Get those hills out of the way early and coast through the rest of the course, which is a great one for setting a personal record (and a Boston qualifier for full marathon runners).

Once you’ve finished the race, make sure to stay for the after-party, an all-day affair in downtown Columbus featuring live music, a beer garden, and a truck giveaway to one lucky marathon or half marathon finisher. The proceeds from the half marathon go to a good cause, so run for good: with over $210,000 donated to charities promoting healthy lifestyles in the race’s first three years.
