Endurance Grid lists 16 trail running races in Indiana, from September 2026 to June 2027 across 12 cities.
The trail running race calendar in Indiana is busiest in October, September, and April, with races most often in Martinsville, Fort Wayne, Bloomington, and Columbus.
Trail running takes the sport off the pavement and onto dirt trails, singletrack, fire roads, and mountain paths. It’s quieter than a road race. Depending on the course, you might spend long stretches alone with the woods and your own breathing.
If you already run roads, trails are a natural next step, but they ask for different things: power on the climbs, control on the descents, and attention to every footfall. There’s a distance for every level, from a rolling trail 5K to 100-mile mountain ultras.
