The start and finish areas provide simple dining and rest facilities exclusively for participants. These areas offer only food and brief rest services; no accommodation is available, so participants must arrange their own lodging.

Withdrawing and the Shuttle Arrangement

If a participant sustains an injury that does not affect their progress, they should proceed to the CP to contact volunteers for withdrawal procedures. Staff will then cut off a corner of the bib and remove the wristband. Withdrawn participants may still use the bib to travel to the finish line and enjoy services such as meal provisions.

The return arrangements for withdrawing participants shall be implemented by the CP coordinators in accordance with the following rules:

● Is there a available return bus service with specified departure and arrival times available at this station?

● Should the health condition of withdrawing participants require immediate return to the starting/ending area?

● At stations or medical points where only small vehicles are permitted, there may be delays in transfers, or participants may need to return to the start/finish area when stations close.

If the event is terminated due to weather conditions, the organizing committee will arrange transportation to promptly return participants from that location to the start and finish area.

If a participant decides to withdraw midway, they must typically return to the previous service point or proceed to the next one to complete withdrawal procedures. If, during the return journey, they encounter a closing staff member and refuse to follow them to the subsequent location, the staff will contact the organizing committee to process the withdrawal on-site and notify the nearest rescue personnel to escort them back to the initial point.

Trail Sign: The event organizing committee has installed numerous reflective route markers along the course for all events to ensure clear visibility for participants in nighttime conditions. If a participant fails to see any marker within 300 meters during their journey, they must immediately turn back along the original path to the nearest marker. All participants must strictly follow the route markings and are prohibited from taking shortcuts without authorization. In case of getting lost, participants should promptly contact the organizing committee for assistance.

Event Prize
