Semi Marathon de Nashville

Semi Marathon de Nashville is held in Nashville, Tennessee, on October 24, 2026, with two distances: a 5K and a half marathon (13.1 miles). The route runs through the streets of a city best known for its music scene, country music in particular.

A city half in late October usually lands at the end of a summer's worth of aerobic work, which is exactly what the distance rewards. Sixteen weeks is the standard build, with the long run climbing to 11 or 12 miles and one tempo run each week at roughly the pace you intend to hold. Urban routes come with corners and surface changes, so run the tangents and expect your watch to read slightly long. The 5K is the alternative if the half is more than your training supports, and it doubles as a hard tune-up for something later in the year.
