Checkpoints and Aid Stations

All rescue points and service stations are under the control of the race committee. Only participants with clearly worn bib numbers can enter the aid stations, which are listed in the race guide and on the official website.

There are two types of aid stations:

ü Simple aid stations: drinking water, energy drinks, cola, coffee, tea, bananas, oranges, nuts, raisins, biscuits, etc.;

ü Full aid stations: in addition to the above, there are various flavors of porridge, noodles, rice balls, steamed buns, ham, coffee, hot chocolate, and bread etc.

To reduce waste, participants should carry a cup or container of at least 150 ml to get drinks from aid stations. Trash cans and trash bags are provided at service points for disposing of waste.

Cutoff Time.

The total cutoff time for each event are as follows:

ü 105K: 29.5 hours

ü 50K: 11 hours

ü 25K: 6 hours

Each event's cutoff time at each checkpoint is clearly marked, based on the time the participant checks in at the checkpoint. Participants must leave before the closure of the checkpoint they enter. The race committee reserves the right to terminate the race or modify the cutoff times of the checkpoints when exceptional weather or other special circumstances occur.

Rest Area

For 105K, a rest area (equipped with a certain number of beds and blankets) is set up in YangDu Village. However, due to traffic restrictions, the time slot for the shuttle buses for participants who withdraw from the race is usually between 06:00-20:00. Outside of this time slot, those who withdraw from the race will rest in the rest area until the following day when they will be transported back to the finish area.

At the finish area, a simple rest area is provided for all participants, but it is only for those who complete the race; the rest area is not for sleeping overnight, so participants should arrange their own accommodation.

Withdrawal and Transportation Arrangement

Unless impaired by injury, participants should withdraw at the checkpoints by notifying the checkpoint staffs and having their wristbands cut off. Participants can still use their race bibs to take transportation, enjoy supplied meals, and rest areas.

Return transport for withdrawals is arranged by the checkpoint staffs based on the following rules:

ü Whether the checkpoint has shuttle buses that can be allocated back to the finish area;

ü Whether the health condition of the withdrawn participant requires prompt return to the finish area;

ü For those checkpoints or medical stations that only allow passage of small vehicles, there may be delays, or those stations will bring the withdrawn participants back to the finish area as they close and evacuate;

ü When weather conditions lead to the termination of the race, the race committee will arrange for vehicles to bring participants from the checkpoint back to the finish area as quickly as possible.

When participants decide to withdraw mid-race, they typically need to make their way back to the previous checkpoint or move forward to the next one to proceed with the withdrawal. If a participant encounters the sweeping staff while heading back to the previous checkpoint and does not wish to follow them to the next one, the sweeping staff will process the withdrawal and cut off their wristband.

Race Course Marking

For all events, a large number of identifiable markers are set up along the route. To aid visibility at night, fluorescent markers will also have reflective strips that are visible when illuminated by a headlamp. If markers are not continually seen within a certain range (within 300 meters), participants should return to the last place with markers. Participants are required to follow the markers and are not allowed to take shortcuts, as off-course paths usually complicate rescue efforts.


All finishers will receive a medal as a souvenir, and additional trophies, pre-tax prize money (CNY, tax is 20%), and prizes will be awarded to podium finishers (announcements will be made before the race).

Penalties and Disqualification

The organizing committee has the authority to penalize the following rule violations:

     - Other violations are judged and penalized by the referee committee;
