2026 STACK UP! Overview

The STACK UP! gives you up to 5 days to participate. Anyone that stacks for at least 30 minutes during that time will be counted!

What is the STACK UP!

Our yearly World Record attempt for "Most People Sport Stacking at Multiple Locations."

• COMMIT to 25 or more stackers who will stack for at least 30 minutes anytime from November 16th to the 20th. (Need cups? We'll loan them to you)
• REGISTER easily online. We request teachers/instructors get together and only register once for your entire school or organization.
• STACK with a fun lineup of sport stacking activities then VERIFY the exact number of unique participants by completing the Online Verification.

New Partnership Announcement!

We’re excited to announce our new partnership with US Games, BSN Sports, and OPEN Phys Ed! As the leader in curriculum development, OPEN is creating brand-new stacking activities that will launch ahead of this year’s STACK UP! event. This partnership brings teachers even more resources to engage students through fun, inclusive, and standards-based activities—helping make STACK UP! bigger and better than ever.

You can find Speed Stacks gear on the US Games website and explore free OPEN resources at open.varsityuniversity.org.

Important Note

We require that all schools and organizations must have 25 or more stackers to register, participate and be counted. (Individuals and families wanting to participate must be part of a group of 25 or more with adult organizer and witness.)
