2027 Winter Night Trail Marathon

The Winter Night Trail Marathon turns Eagle Creek Park into a stage for winter running after dark. Now in its 13th year, this Indianapolis race has built a quiet following—about 138 finishers in recent editions, with roughly a quarter of them returning for more. It's a small field, but one that grows year by year, drawn by the rare chance to race trails at night.

Starting at 6:00 PM, the half marathon unfolds on the park's trails under winter skies. Conditions are reliably cold—temperatures typically hover between 22 and 35°F—and the darkness adds a layer of challenge that daylight races can't match. The course is a true trail test, demanding focus and sturdy footing, with the added thrill of navigating by headlamp.

What makes this race special isn't the crowds or the spectacle, but the shared adventure among those who toe the line. It's a race that rewards preparation and grit, and the finish brings a hard-won sense of accomplishment. For runners seeking a different kind of half marathon—one where the elements and the night are part of the story—this Indianapolis event delivers.
