However, if they ultimately cannot complete the obstacle, a band will be removed. • No Retries Allowed for Hanging obstacles: Participants are not allowed to retry hanging obstacles (rigs, rings, etc.) to avoid losing a band. If they ultimately cannot complete the obstacle the first time, a band will be removed. • Finishing Requirements: Complete the race with one of the following: • All 3 bands intact (no penalty), • 2 bands and 1 penalty loop, or • 1 band and 2 penalty loops. • Penalty Loop: Located just before the finish line. • All Bands Lost: Participants will be marked as “Did Not Complete” (DNC) if all bands are lost.
