Fenced sections at the start line grouping runners by expected pace to prevent congestion.
Chip Time

Starting a race but not completing it. No shame — every runner has a DNF story.
Aid Station
On-course stops offering water, sports drinks, gels, and sometimes medical support.
Wave Start
Staggered starting format where groups of runners begin at timed intervals (every 5–15 minutes) to reduce congestion.
DNQ (Did Not Qualify)
