Invited elite athletes must check in at the exclusive check-in area and present the original passport or ID document during check-in.

(V) Cut-off Time To ensure the safety of participants, the race course will have time-limited traffic closures. Each section of the race course will have a cut-off time. Once the cut-off time is reached, the corresponding timing carpet will stop working, and the road section will gradually reopen to traffic. Participants who have not finished the corresponding distance within the cut-off time must stop the race and exit the course to avoid danger. Participants can take the sweep bus provided by the organizing committee to the finish area.
