The big 3 races are working together with the ASTM to create safety standards, to try and make all races more safe for participants (and possibly cheaper eventually thanks to cheaper insurance as a result).
The obstacle course racing community has grown significantly in recent years. Designers, owners, builders, and operators could benefit from this proposed standard, currently known as the work item: “New Practice for Design, Construction, Operation, Inspection, Safety, and Maintenance of Land-Based Pedestrian Obstacle Courses” (WK54714). The scope of this proposed standard also includes removing obvious hazardous conditions by logically applying existing standards and model codes. Also according to its scope, this standard will not address attractions such as ropes courses or zip lines, nor will it purport to address all of the safety concerns associated with the standard’s use. (It will be the responsibility of the user of the standard to establish appropriate safety and health practices prior to use.)
