Smyrna — On Aug. 4, CrossFit 285 at 4620 S. Atlanta Road will complete a partner workout that has become an annual tradition and fundraiser to honor fallen military heroes as part of the 31 Heroes Project.

After a helicopter crash in Afghanistan killed 31 service members Aug. 6, 2011, the project was created to honor the men and support their families. In its first annual workout, just four weeks after the crash, more than 10,000 people participated and more than $300,000 was raised and given directly to the affected families.

Each step in the workout bears special significance. It is 31 minutes long, providing one minute in remembrance for each life lost, the rep scheme, 8-6-11, corresponds to the date of the crash, and the cooperative nature of a partner workout signifies how the men were from multiple branches of the military, working together as a team.

The workout is open to the public. The registration fee is $31. Funds will be disbursed to Snowball Express, the Travis Manion Foundation, and the affected families of the 2011 crash.
