This is a nonstop race through a remote, largely uninhabited part of the Gobi Desert. Support along the course is intentionally minimal.

Rest stations are placed approximately every 40 kilometers (10 stations total). At rest stations, participants can access their personal drop-off boxes, packed and handed over before the race. Communal tents, sleeping mats, and hot and cold drinking water are provided. There is no time limit at rest stations.

Checkpoints are placed roughly every 8 to 12 kilometers between rest stations. Their primary role is safety and tracking. Water is available at checkpoints, but no additional supplies or rest facilities are provided. Maximum rest time at a checkpoint is 2 hours.

Between checkpoints, on the open course, the maximum rest time is 1 hour. Exceeding rest time limits results in time penalties.

Drop-off boxes: Each participant receives standardized storage boxes (54 x 40 x 33 cm, max 10.5 kg each) for each rest station. Boxes must be packed and handed over before the race. The organizing committee transports them to the corresponding rest station. There is no transfer service between stations during the race.

The Ultra Gobi 400km is a fully self-supported race. Between rest stations, you carry everything you need: food, personal medication, and all mandatory equipment.

Mandatory gear inspections take place at the start line and at designated checkpoints during the race. Missing items result in time penalties or, in serious cases, disqualification.

All participants must wear a "Gobi Eye" GPS tracker provided by the organizing committee for real-time location tracking throughout the race.

The full mandatory equipment list is published in the Race Regulations. Key items include navigation equipment (personal GPS device), emergency shelter, headlamp, first aid supplies, and sufficient food between rest stations.

Every runner wears a GPS tracker ("Gobi Eye") provided by the organizing committee, allowing the race team to monitor all participants in real time.

Checkpoints are positioned every 8 to 12 kilometers along the course. Trained volunteers and race officials are stationed at all checkpoints and rest stations. Medical staff are available on the course and at designated rest stations.

If a runner needs assistance, the GPS tracker has an emergency alert function. The race committee can dispatch support to any location on the course.

Participants who withdraw can enter a 30-minute observation period before formally signing a withdrawal declaration. One re-entry per race is permitted (with a 3-hour time penalty), subject to medical clearance and approval by the Race Director.

All participants must carry personal navigation equipment and be proficient in its use. The course is not marked. Self-navigation is a core element of the race.
