Sam Costa Half Marathon and Quarter Marathon - presented by Indy Runners and Walkers

Join fellow runners and walkers at the Sam Costa Half Marathon and Quarter Marathon, presented by Indy Runners and Walkers, on Saturday, March 21, 2026, in scenic Carmel, Indiana. As Indiana's oldest road race, celebrating its 55th anniversary in 2026, the Sam Costa boasts a rich history dating back to 1970, named in honor of a dedicated Chicago detective who loved the sport. This event is renowned for its participant-friendly atmosphere and "by runners for runners" philosophy, ensuring a welcoming experience whether you tackle the challenging 13.109-mile half marathon or the accessible 6.554-mile quarter marathon.

The USATF-certified course is primarily fast and flat, traversing paved suburban and rural roads that offer picturesque central Indiana scenery, including sections along the White River. While generally swift, runners will encounter some rolling hills, notably a climb around mile 2.5 and the race's most significant ascent around mile 6, with a final uphill push to the finish. Aid stations are plentiful and well-supported, providing necessary hydration along the route. Typical race day conditions in late March bring highs around 55°F and lows around 35°F, with a relatively low 18% chance of precipitation, offering crisp running weather.

The Sam Costa Half Marathon and Quarter Marathon stands out for its intimate feel, avoiding the crowds of larger city races and focusing on the pure joy of running. Northview Christian Life Church provides a comfortable indoor space for pre- and post-race activities, a welcome amenity. The Half Marathon has a 3-hour time limit, and the Quarter Marathon is particularly accommodating for walkers. All net proceeds from the race directly benefit the Indianapolis running and walking community through high school scholarships, training programs, and community events, making your participation a stride for a greater cause.
