About
Sloth Run Half Marathon is held on August 28, 2027, in the heart of Manhattan, New York. Three distances are offered: the half marathon (13.1 mi), a 10K (6.2 mi) and a 5K (3.1 mi). Start times are not listed in our records.
A race that names itself after the slowest animal in the world is setting expectations deliberately, and in a New York August that is sound advice rather than a joke. Run it at an effort you could hold while talking, take the water stations seriously, and treat the finish as the objective — the autumn calendar is where the times are made.
