The Fittest 5k by Fitness Coliseum
The event on 08/22/2026 in Owosso, Michigan, at 210 S Water St is a 5k that alternates running sections with functional fitness tests. Each athlete completes the full distance while stopping between runs to perform prescribed movements. Participants may run, walk, or use a combination of both for the distance.
There are two divisions. The "Competitive" division uses set weights, box heights, and movement standards differentiated for men and women. The "Here for a Good Time" division allows athletes to choose weights, modify movements, or substitute step ups for box jumps. Weights listed for the competitive division use men/women values.
The 2026 format alternates runs and tests in the following sequence: 800 m run, 20 pull ups, 400 m run, 20 double dumbbell squats (35/25), 400 m run, 15/12 calorie ski, 400 m run, 20 box jumps, 400 m run, 15/12 calorie row, 400 m run, 200 m farmers carry (53/35), 400 m run, 20 single DB lunges (50/40), 400 m run, 20 plate touches (45/35), 400 m run, 20 burpees, 800 m run.
