The race climbs from the gun: 188 m over the first 5 km. Do not chase the crowd, the two minutes you win here get taken back with interest.
The steepest wall stands between km 14 and km 18: 337 m over 3.6 km at 9% average, its steepest roughly 250 m section averaging 24%. Kilometre by kilometre: km 15 40 m, km 16 72 m, km 17 111 m, km 18 138 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The backbone of the course runs from km 30 to km 38: 501 m over 8 km at 6% average, its steepest roughly 250 m section averaging 17%. Heaviest kilometres: km 36 111 m, km 34 99 m, km 32 74 m, km 35 74 m. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.
The longest drag runs from km 62 to km 71: net 344 m over 8.8 km at 4% average, its steepest roughly 250 m section averaging 18%, 431 m of climbing in total with 87 m given back. Heaviest kilometres: km 67 87 m, km 70 61 m, km 69 59 m, km 68 48 m. By the time you start it, about 63% of the day's climbing is behind you. Forcing a run up this climb takes more than it gives. Hike it and keep your heart rate away from the ceiling.
The longest descent starts at km 37 and loses 357 m by km 46 at 4% average, its steepest roughly 250 m section averaging 14%. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 93 averages 32% on the GPX trace over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.
The last 6 km drop 598 m first and then climb 299 m. Empty your legs on the descent and that final rise takes the payment.
The leg from Sicha Village to Taobeiying Village is long and unsupported: 14 km and 643 m of climbing with no aid in between, so leave Sicha Village with full capacity.
A steep pitch starts within about 0.5 km of Chahan Tuoluo Village; keep the stop short and do not enter it on cooled-down legs.
You reach the climb after Huangtuyao with about 521 m of descent already in your quads; treat its first half as recovery effort.
- The organiser lists 3800 m of climbing; the published GPX measures 4023 m. The technical course notes use the published GPX measurement.
- This course reaches 1516 m. A separate forecast for the high-point coordinate gives 3°C to 18°C, wind up to 14 km/h (a light breeze). It is a daily forecast for that coordinate, so arrival time can still change what you encounter.
- Sunset is 18:36 and the finish cut-off is 12:00. A runner using the full time allowance spends the final 11 hours 20 minutes in darkness.
- Get the headtorch out before sunset and keep spare batteries or a power bank dry and immediately accessible. A spare buried at the bottom of the pack is not an emergency spare.
- Check reflective course markers regularly in the dark. If the markings disappear, stop moving forward, return to the last marker and confirm the route against the GPX or organiser app.
- Consider bringing poles. The course averages 40 m of gain per km and the longest climb averaging over 5% runs 8 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.

- Drinks only, no food, at Xiaohongni Bay (km 56) and Tujingzi Village (km 74). Loosen the flask caps on approach; with no queue, refill and leave in 20-30 seconds. Carry the food you will need from the previous station.
- Hot food is served at Taobeiying Village (km 22) and Chahan Tuoluo Village (km 29) and 5 more. If your stomach and race plan call for it, make this a deliberate 3-5 minute stop; do not sit down simply because hot food is available. Restart gently and let your stomach settle before lifting the effort.
- Food is available at Sicha Village (km 8). Decide what you need before reaching the table; without a planned special task, collect food and fluids and leave within 60-90 seconds. Finish eating on the next calm, suitable section.
- Drop bag at Wushijia (km 47). Write down the equipment and food you expect to replace before the race so the decision is already made when you arrive.
- The last aid station is Cuiping'an Village (km 91), leaving 9 km to the finish. After that you are on what you carry.
- Another heavy leg runs from Cuiping'an Village (km 91) to Dajingmen (km 101): 10 km with 559 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Dajingmen (km 0), Sicha Village (km 8), Taobeiying Village (km 22), Chahan Tuoluo Village (km 29), Yaozigou (km 38), Wushijia (km 47), Huangtuyao (km 62), Tujingzi Village (km 74), Qinghe Village (km 81), Cuiping'an Village (km 91), and Dajingmen (km 101). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- About 2 km after Wushijia (km 47), a roughly 250 m section averaging 19% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.
- The overall cut-off is 26h, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
- Relative to distance and climbing, the tightest official time budget runs from Start to Taobeiying Village (km 22): the official time budget is 5h for 22 km and 1019 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

- Hot food is served at Sicha Village (km 8) and Huangtuyao Village (km 14) and 2 more. If your stomach and race plan call for it, make this a deliberate 3-5 minute stop; do not sit down simply because hot food is available. Restart gently and let your stomach settle before lifting the effort.
- The last aid station is Cuiping'an Village (km 43), leaving 9 km to the finish. After that you are on what you carry.
- The heaviest leg runs from Cuiping'an Village (km 43) to Dajingmen (km 53): 10 km with 559 m of climbing. Treat it as the slowest part of your day and get your food out before it.
- Medical support is available at Dajingmen (km 0), Sicha Village (km 8), Huangtuyao Village (km 14), Tujingzi Village (km 26), Qinghe Village (km 33), Cuiping'an Village (km 43), and Dajingmen (km 53). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
- About 0.8 km after Sicha Village (km 8), a roughly 250 m section averaging 14% begins. Choose food you know you digest easily and fill the bottles, then enter the climb at a controlled effort.
- The overall cut-off is 14h, including all checkpoint stops. Build the plan around the official leg budgets below, not a flat-course average pace.
- Relative to distance and climbing, the tightest official time budget runs from Start to Huangtuyao Village (km 14): the official time budget is 3h for 14 km and 616 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

The published GPX measures 31 km with 1471 m of climbing, 48 m per km. The course sits between 795 m and 1161 m of altitude. 44% of the gain sits in the first half.
- 0-9.7 km · Start → Tanyi Valley: 438 m up / 317 m down; the stretch climbs.
- 9.7-17 km · Tanyi Valley → Caishi Village: 259 m up / 214 m down; the stretch keeps rolling.
- 17-21 km · Caishi Village → Cuiping'an Village: 206 m up / 240 m down; the stretch keeps rolling.
- 21-31 km · Cuiping'an Village → Finish: 568 m up / 736 m down; the stretch descends.
The race climbs from the gun: 25 m over the first 2.5 km. Do not chase the crowd, the two minutes you win here get taken back with interest.
The backbone of the course runs from km 0 to km 8: net 280 m over 8.1 km at 3% average, its steepest roughly 250 m section averaging 19%, 433 m of climbing in total with 153 m given back. Heaviest kilometres: km 6 90 m, km 8 80 m, km 4 65 m, km 5 54 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.
The steepest wall stands between km 15 and km 19: net 222 m over 3.9 km at 6% average, its steepest roughly 250 m section averaging 32% on the GPX trace, 249 m of climbing in total with 27 m given back. Kilometre by kilometre: km 16 38 m, km 17 27 m, km 18 84 m, km 19 102 m. Trying to run this costs far more than it saves. Shorten the stride, lean on the poles, keep moving.
The climb between km 21 and km 24: net 178 m over 3.1 km at 6% average, its steepest roughly 250 m section averaging 11%, 236 m of climbing in total with 58 m given back. Kilometre by kilometre: km 22 46 m, km 23 76 m, km 24 75 m. By the time you start it, about 61% of the day's climbing is behind you. Forcing a run up this climb takes more than it gives. Hike it and keep your heart rate away from the ceiling.
The longest descent starts at km 24 and loses 344 m by km 31 at 5% average, its steepest roughly 250 m section averaging 34% on the GPX trace. Its length can load the quads, so begin under control and build rhythm only when the ground and visibility allow it. The drop at km 19 averages 24% over its steepest roughly 250 m section; shorten the stride, stay balanced and set speed to the ground instead of braking continuously.
The last 3.7 km drop 205 m. If anything is left in your legs, spend it here.
- This course reaches 1161 m. A separate forecast for the high-point coordinate gives 6°C to 21°C, wind up to 14 km/h (a light breeze). It is a daily forecast for that coordinate, so arrival time can still change what you encounter.
- Even at cut-off pace you finish 2 hours 6 minutes before sunset. This one is run entirely in daylight.
- Consider bringing poles. The course averages 48 m of gain per km and the longest climb averaging over 5% runs 3.9 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
- 16% of the course is steep descent. Increase your cadence instead of braking, or your quads go early.
Course-profile notes are generated from GPX grade data; terrain, rules, aid stations and weather are added only when separately sourced.
