Your city. Your STACK. Your time to beat.
Orange County is a confirmed location for the 2027 Spring/Summer STACK season. The exact stadium and race date will be announced. Registration for this race is not open yet.
The 2027 Stack
Seven exercise zones, with running before each one. Begin with a 660 m run, then return to the track for a 440 m run before each of the remaining six zones. The annual workout stays the same all season: kettlebell Russian Twists and Squat Walks; Standing Floor to Ceiling; Burpees; Supine Shoulder to Sky (Skull Crushers); Push-Up Release and Full-Body Crunches; Plate Curl 'Around the World'; and Arms-Up Lunges with a Medicine Ball to the finish.
Your Course
Running laps go counter-clockwise in lanes 5–8. Start in lanes 1–4, then gradually enter lanes 5–8 after the first 100 m. The final Arms-Up Lunges also go counter-clockwise, in lanes 1–4. Six exercise zones are arranged across the football field, and the seventh finishes on the track. Canopies cover a good portion of exercises 2, 3, 4 and 5. See the 2027 STACK workout and course diagram for the organizer-provided movements, repetitions, weights and flow.

Your Cheering Section
Bring your friends and family. The stadium setting keeps the action close, with a 20-yard spectator area between the 40-yard lines. At the 50-yard line, donate to help end human trafficking while watching a STACK team member do 1 Burpee per dollar donated. The challenge should feel real, and the day should feel fun.
