01 / Course overview
Why the 100K is the hardest course.
The Dream Wall 100 is the highest and longest course in the 2026 race. It links the Shuangqiaogou, Haizi and Changping valleys, with ice, snow, loose rubble, steep technical descents and a run through a full day and night at altitude. Organisers rank it first for difficulty and overall intensity.

2026 course changes.
1. Distance re-measured by the organiser in mid-September. The 2025 race was shortened by snow.
2. The Bajiaopeng Lake technical section is back in the route. In 2025 it was removed because of snow above 3,800 m.
3. The Haizi valley is fully open, including Da Haizi, the lakeside path at Hua Haizi and the return past Dahuangpengzi.
4. Reroutes or section closures remain possible in severe weather (heavy snow, hail, strong wind).

Finish-time estimates.
The organiser bases these on 2025 times, which were 2–4 hours faster on the shortened course. Do not use a 2025 result to predict a 2026 finish.

| Runner profile | Estimated finish |
|---|---|
| Advanced high-altitude runners: 4,500 m+ and long night experience, fully equipped | 24–28 hours |
| Experienced at 100K, limited high-altitude racing, aiming to finish steadily | 28–30 hours |
| Finishing before the cut-off, walking most of the course, slowing on technical sections | 30–32 hours |
02 / Route and checkpoints
Stage by stage.
Stations and distances as given in the official article. Where the article does not state a distance or altitude, the cell is left blank.
| Point | Altitude | Km | What to know |
|---|---|---|---|
| Hongshulin, start | 3,838 m | 0 | Start. Descend the Shuangqiaogou wooden boardwalk and forest paths. The first 5 km can have ice on the boardwalk. |
| CP1 Sigunacuo | 8.1 km | Water. | |
| CP2 Yunduan Mountain | 17.2 km | Hot porridge and other carbohydrates. | |
| CP3 Wuse Mountain | 3,245 m | 27.7 km | Last station before the Tiaoshuigou climb. Put on crampons and waterproof gloves here. Keep insulated layers where you can reach them in the pack. |
| Tiaoshuigou Pass | 4,560 m | Highest point of the course. About 5 km and 1,322 m of climbing from Wuse Mountain, steep at the end over frozen rubble and snow. Strong wind; do not stop to take photos. | |
| Tiaoshuigou Cowshed | 33.9 km | Short rest. Remove crampons only if the descent has no snow. | |
| CP5 Wuye Abalang | 3,180 m | 38.4 km | Clothing change. Change socks, eat hot food, treat blisters. Gear check on leaving. Most runners are in the night by this point. |
| Bajiaopeng Lake | 4,455 m | Rubble mixed with ice, steep ascent and descent, exposed traverses. Waterproof socks matter here. Change socks at CP5 if the first half is wet. | |
| CP6 Dajianbao | Withdrawal point. If the body is signalling trouble, stop here. Going above 4,000 m when already unwell is not advisable. | ||
| CP8 Da Haizi | Important night station for the 100K and 70K. Drink and take hot food. | ||
| CP9 Dahuangpengzi | 3,954 m | Timing point only. No supply. | |
| CP12 Hua Haizi | 3,789 m | 63.4 km | Rest and refuel. A steep zigzag climb of about 1 km and 350 m follows; you will need to stop to breathe. |
| CP13 Zhongliangzi | 70.3 km | Rolling ground above 4,000 m, then a 3 km technical descent of over 800 m. Arriving after 25 hours leaves about 7 hours before the final cut-off. | |
| CP14 Xiagan Haizi | Moved here from the old Kushutan station after some runners went wrong at the old site. | ||
| CP15 Muluozi | 83.7 km | About 4 km from CP14 along the right-hand side of the Changping valley trail. | |
| CP16 Lama Temple | Split point. 100K and 70K turn at the Lama Temple junction and take the road back to the main venue; 50K and 35K go to the Lama Temple loop. | ||
| Finish, main venue | 99.4 km | The 100K and 70K return by road to the main venue, about 5.5 km of gentle downhill. |
03 / Danger points
Three places to slow down.
Tiaoshuigou Pass, 4,560 m
Highest point, thin air, icy slope. This is the most common site of withdrawals and accidents. Do not linger for photos; the wind is strong.
Bajiaopeng Lake, 4,455 m
Rubble mixed with ice, a steep climb and descent, and narrow traverses. Slow down and keep three points of contact. In 2025 about 20 cm of snow cancelled this section; in 2026 it is back in the route.
Zhongliangzi section
The last major climb, followed by a steep descent. Wet or muddy ground after rain or snow is very slippery. Do not overtake on the descent unless the path is clear.
04 / Pacing and night running
How to run it.
- Hold back for the first 28 km. The flat, easy-looking section is where runners go too fast, then collapse on the Tiaoshuigou climb. The article suggests running about 30 seconds per km slower than plan.
- The second half of the course is typically 10 minutes slower per km than the first, and can be an hour or more slower overall because of altitude and fatigue.
- Technical sections are slow. In 2025, the stretch from Dajianbao to Zhongliangzi (about 23 km) took nearly 10 hours.
- Three stations are above 4,000 m. Persistent headache, vomiting or loss of coordination: descend immediately.
Night. About 60% of runners enter the night between Wuse Mountain and Wuye Abalang. The Haizi valley then means many hours of continuous effort. The article suggests reaching CP5 (38.4 km) in 8–9 hours; past 10.5 hours means a long, hard night ahead.
05 / Gear for this course
What the article recommends.
Mandatory equipment for every category is in the race-week guide. This list is the 100K-specific advice from the article.
| Crampons | Required. Tiaoshuigou Pass and Bajiaopeng Lake are shaded and icy during the race. |
| Two headlamps, or one plus a spare | Battery drains quickly at altitude. Some runners spend two nights on course. |
| Insulated jacket, waterproof gloves, warm hat that covers the ears | Wind at the passes. Night temperatures can fall to minus 10 °C or below. In 2025 some runners' fingers nearly froze on the pass. |
| Waterproof socks | Wet or muddy sections, and a few places where you may need to cross water. |
| Thermos | Water in bladders can freeze above 3,800 m. Hot water helps if you feel unwell. |
| Carbon trekking poles | They reduce load on the big climbs and steep descents, and are light to hold for long periods. |
