Less guesswork. More starting-line energy.

An outdoor fitness race at a football-field and track stadium. The 2027 workout has seven exercise zones, with running before each zone. Finish the full STACK as fast as you can. See the 2027 STACK page for the workout and course flow.

For Exercise 1, the kettlebell will be 30lb for Men & 20lb for Women. For Exercise 2, the weight will be 25lb free weights for Men and 15lb for Women. For Exercise 4, the weights will be 20lb free weights for Men and 10lb for Women. For Exercise 6, the Plate will weigh 25lb for Men and 15lb for Women. For Exercise 7, the Medicine Ball will weigh 20lb for Men and 10lb for Women.

The same STACK is used throughout the 2027 season. Train for the published workout, race it, and come back to improve your time.

The goal is a fun, challenging race for recreational competitors as well as experienced athletes. The 2027 workout, weights, repetitions, and distances are published so you can prepare. Any entry categories or scaling options will be announced separately.

The design target is about an hour for an average competitor. Your time will depend on your pace and the final workout; this is a target, not a time guarantee.

Orange County and San Jose are the confirmed locations for the 2027 Spring/Summer STACK season. Exact event dates and stadiums will be announced.

Race sign-ups are planned for late January 2027. Competitors on the email list will be notified 72 hours before the STACK 2027 sign-up date is publicly announced. Spaces fill fast. Joining the list or creating an account does not reserve an entry.

Canopies will cover a good portion of exercises 2, 3, 4 and 5: Standing Floor to Ceiling, Burpees, Supine Shoulder to Sky, and Push-Up Release & Full-Body Crunches. Running and the other stations remain outdoors.

Absolutely—that’s part of the idea. The stadium layout is designed to keep the race in view, with designated spectator areas between the 40-yard lines, a 20-yard space separate from competitors. Final access, admission, and spectator guidance will be announced.

Our plan puts a Stacks team member at the 50-yard line in the center of the field doing one Burpee for every dollar donated toward the fight against human trafficking. People who want to help can join the reps in the designated area, away from the race course. Donation arrangements and participation details will be announced.

The planned beneficiaries are A21 and the Tim Tebow Foundation, whose work includes fighting human trafficking. We’ll share the donation route, allocation, and confirmed arrangements before the event. Stacks is not collecting donations on this site yet.

The planned bag includes a water bottle, a Stacks Fitness Racing T-shirt, and a voucher for a free stack of pancakes. The idea is to redeem the pancakes before or after your race. Final items, sizing, and redemption conditions will be confirmed.

Your email stays within our database and is never sold. We use your opt-in for STACK registration announcements and race updates. Leaving your email does not create a race entry; creating a member account is optional.

No. The interest list just needs your email and consent to receive registration announcements and Stacks race updates. A member profile is separate; neither signs you up for a race.

Account signup does not subscribe you to marketing. Registration announcements require a separate, explicit email opt-in. If you enter a race, essential confirmation, cancellation, and race updates go to your account email.

Use the confirmation link after signup. If it’s missing, check spam or request another from the sign-in page. Password recovery is also available there. Account email verification is separate from the race interest list.
