Sam Costa Half and Quarter Marathons

Lace up for a piece of Indiana running history at the Sam Costa Half and Quarter Marathons on March 21, 2026, in scenic Carmel, IN. As the oldest race in Indiana, celebrating its 55th running, this event carries a rich legacy, initiated by dedicated educators and coaches in 1970 and now presented by Indy Runners and Walkers, the state's largest RRCA-affiliated running club. Known for its participant-friendly atmosphere, the Sam Costa offers a more intimate race experience compared to larger city events, drawing around 400-500 finishers combined. All net proceeds from your participation directly benefit the Indianapolis running community through high school scholarships and various programs promoting a healthy lifestyle.

The courses, updated in 2024 for improved safety and fewer turns, are expected to remain the same for 2026, featuring a fast and mostly flat profile along paved surfaces. Runners will enjoy picturesque suburban and rural country roads, with both distances starting and finishing at Northview Church. The half marathon presents a challenging test of early-season fitness, while the quarter marathon provides an accessible distance for those building endurance, with walkers strongly encouraged in the shorter event. Typical race day conditions in late March include comfortable highs around 55F and lows around 35F, with an 18% chance of precipitation, offering ideal running weather.

Aid stations are plentiful and well-supported with volunteers, ensuring you stay hydrated and motivated throughout the course. Pre- and post-race activities, including packet pickup and the awards ceremony, are conveniently located indoors at the Northview Church Student Center, offering a warm and welcoming space before and after your run. With a generous 3-hour time limit for the half marathon (13:45 min/mile pace) and no time limit for the quarter marathon, the Sam Costa fosters a supportive environment for runners and walkers of all levels to achieve their personal best.
