The Fittest 5k by Fitness Coliseum 2026

The race.

The Fittest 5K by Fitness Coliseum takes place on August 22, 2026, in Owosso, Michigan. The 5K distance is divided into running sections alternating with functional fitness movements including pull-ups or ring rows, dumbbell squats, ski machine, box jumps, rowing, farmers carries, lunges, plate touches, and burpees. Two divisions are offered: Competitive, with set weights and heights for men and women, and Here for a Good Time, allowing athletes to scale weights and movements to their fitness level. Participants may run, walk, or combine both for the entire distance. Athletes compete in staggered heats of 3–5 people starting three minutes apart; final heat assignments and times will be released the Wednesday before the race. Finishers receive a tank top; registration must close by August 7 to guarantee a shirt. Awards are given to top three finishers in Competitive and Here for a Good Time divisions by gender, plus separate categories for Masters (50+) and Youth (under 18).
