A formally structured freerunning competition circuit that prohibits all active augmentation during runs — no chrome-assist reflexes, no BCI-paced movement, no subdermal impact dampening. Participants must disable or physically cap their augments before a certified official, then complete courses built across GLMZ's exterior scaffold networks, construction remnants, and the famous 'Rib Cage' — the exposed superstructure of a never-finished Tier 3 arcology tower in the Waukee Corridor. What began in 2209 as a protest against augmented leagues pricing out unaugmented athletes has evolved into a fiercely respected discipline, with its own aesthetic philosophy: 'bone and breath,' meaning the body as it was born. Crowds are loud, betting is heavy, and the courses are brutally difficult — designed by a collective called the Framebuilders who treat course design as architectural art.
