Boo Run 5K & Mini Monster Mile Run

Boo Run 5K & Mini Monster Mile Run is held in Duncan, South Carolina, on October 31, 2026, under the Spartanburg YMCA banner. The 5K covers 3.1 miles and starts at 8:30 a.m., while the Mini Monster Mile follows at 9:30 a.m. for anyone wanting a shorter distance.

The hour between the two races looks deliberate: adults can finish, catch their breath and still be on the sidelines when the mile goes off. If you are racing the 5K, keep the final week light, with a couple of short faster efforts and nothing heavy in the last three days, and give yourself a real warm-up, since the distance leaves no room to ease into the pace. Children running the mile need no preparation beyond being used to moving for ten minutes at a time.
