What the weather is usually like here

  • Over the last 5 years this week typically ran 11°C to 18°C here, with a high of 23°C and a low of 2°C.
  • 46% of those days saw rain. A real forecast lands about two weeks out and will appear here then.
  • Typical daily maximum wind was 12 km/h (a light breeze), with 34 km/h the highest value in the sample.
  • Sunrise 07:19, sunset 18:03.

The race is more than two weeks out, so these are averages of recent years for the same week, not a forecast. A real forecast appears here closer to the day.

The published GPX measures 96 km with 3709 m of climbing, 39 m per km. The course sits between 464 m and 1103 m of altitude. 61% of the gain sits in the first half.

  • 0-11 km · Start → Puguang Primary School: 678 m up / 433 m down; the stretch climbs.
  • 11-18 km · Puguang Primary School → Chayuangou: 476 m up / 245 m down; the stretch climbs.

  • 88-96 km · Shanshui Rural Family Inn → Finish: 59 m up / 560 m down; the stretch descends.

The race climbs from the gun: 394 m over the first 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 5: 467 m over 5.2 km at 9% average, its steepest roughly 250 m section averaging 25%. Kilometre by kilometre: km 2 41 m, km 3 125 m, km 4 64 m, km 5 163 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The late climb from km 78 to km 83: net 309 m over 4.7 km at 7% average, its steepest roughly 250 m section averaging 15%, 388 m of climbing in total with 79 m given back. Kilometre by kilometre: km 79 69 m, km 80 96 m, km 81 76 m, km 82 68 m, km 83 89 m. By the time you start it, about 83% of the day's climbing is behind you. At this point in the day most runners walk this gradient. Settle into a hiking rhythm and let the metres come.

The longest descent starts at km 84 and loses 573 m by km 96 at 5% average, its steepest roughly 250 m section averaging 20%. 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 23 averages 25% 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 429 m. If anything is left in your legs, spend it here.

You reach the climb after Puguang Primary School with about 433 m of descent already in your quads; treat its first half as recovery effort.

The leg from Gaomiaopu to Shanshui Rural Family Inn is long and unsupported: 12 km and 587 m of climbing with no aid in between, so leave Gaomiaopu with full capacity.

  • The organiser lists 104 km; the published GPX measures 96.1 km. The technical course notes use the published GPX measurement.
  • This course reaches 1103 m. At the high-point coordinate, the same week historically ran 8°C to 15°C. Typical daily maximum wind was 11 km/h, reaching 34 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
  • Sunset is 18:03 and the finish cut-off is 23:00. A runner using the full time allowance spends the final 10 hours 19 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.
  • At cut-off pace you run into a second night. Plan the sleep question before race day: an hour gained on the first night costs two on the second.
  • Consider bringing poles. The course averages 39 m of gain per km and the longest climb averaging over 5% runs 5.2 km; if you have trained with them and the organiser allows them, use them on the climbs and stow them on runnable ground.
  • The climbing is stacked into the first half. Start easy; even with less climbing later, the descents and accumulated fatigue still have to be managed.
  • Point to point: the finish sits 22.7 km from the start as the crow flies. Sort the shuttle and your drop bag before race day.

  • Drinks only; arrive carrying your own food.
  • Your drop bag waits here; work off your prepared list.
  • Crew access is allowed here.
  • A heavy leg is next: 11 km with 340 m of climbing.
  • Cut-off: 12h 30m after the start.

South Gate of Jianmen Passkm 66

  • Collect food and fluids and leave within 60-90 seconds.
  • Crew access is allowed here.
  • A heavy leg is next: 10 km with 420 m of climbing.
  • Cut-off: 18h after the start.

Gaomiaopukm 76

  • Drinks only; arrive carrying your own food.
  • A heavy leg is next: 12 km with 561 m of climbing.
  • The longest unsupported stretch starts here: 12 km. Leave with full capacity.
  • Cut-off: 21h after the start.
  • The longest stretch between official aid stations runs from Gaomiaopu (km 76) to Shanshui Rural Family Inn (km 88): 12 km, with 561 m of climbing in between. Top up at Gaomiaopu and size what you carry to the expected duration and your own drinking rate.
  • Drinks only, no food, at Shuhan Courier Station (km 45) and Gaomiaopu (km 76) and 1 more. 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.
  • Puguang Primary School (km 11) is a timing point only, with nothing on the table.
  • Hot food is served at Chayuangou (km 18) and Yinxi Village (km 29) and 3 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 South Gate of Jianmen Pass (km 66). 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 Shuhan Courier Station (km 45). Write down the equipment and food you expect to replace before the race so the decision is already made when you arrive.
  • Crew support is permitted only at Shuhan Courier Station (km 45) and South Gate of Jianmen Pass (km 66). This is not the same as a drop bag: plan equipment and food hand-offs around these stations, then verify wristband, bag and transport rules with the organiser.
  • The last aid station is Zhaohua Ancient Town (km 97), leaving 7 km to the finish. After that you are on what you carry.
  • The heaviest leg runs from Dashudao Buye Sanguo Town (km 0) to Puguang Primary School (km 11): 11 km with 662 m of climbing. Treat it as the slowest part of your day and get your food out before it.
  • Medical support is available at Dashudao Buye Sanguo Town (km 0), Puguang Primary School (km 11), Chayuangou (km 18), Yinxi Village (km 29), Chaotianping (km 35), Shuhan Courier Station (km 45), Cuiyunlang Corridor (km 56), South Gate of Jianmen Pass (km 66), Gaomiaopu (km 76), and Zhaohua Ancient Town (km 97). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
  • The climbing starts the moment you leave Puguang Primary School (km 11): the steepest roughly 250 m section averages 26%. Nothing is served at this point, so arrive already stocked from the previous aid station, then begin the climb under control.
  • Relative to distance and climbing, the tightest official time budget runs from Gaomiaopu (km 76) to Shanshui Rural Family Inn (km 88): the official time budget is 3h for 12 km and 587 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

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 Niutou Village (km 13). 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.
  • The last aid station is Shanshui Rural Family Inn (km 33), leaving 9 km to the finish. After that you are on what you carry.
  • Another heavy leg runs from Niutou Village (km 13) to Dachaoyi Courier Station (km 26): 13 km with 683 m of climbing. Treat it as the slowest part of your day and get your food out before it.
  • Medical support is available at Zhaohua Ancient Town (km 0), Niutou Village (km 13), Dachaoyi Courier Station (km 26), Shanshui Rural Family Inn (km 33), and Zhaohua Ancient Town (km 42). If something is wrong with your feet or your stomach, deal with it there rather than pushing on.
  • About 2 km after Dachaoyi Courier Station (km 26), a roughly 250 m section averaging 15% 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 158h, 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 Niutou Village (km 13) to Shanshui Rural Family Inn (km 33): the official time budget is 1h for 20 km and 1054 m of climbing. Station stops come out of that same budget, so do not enter the leg already behind schedule.

Plan your cutoffs for this course

21.5K course22 km · 872 m gain · 30% uphill · 2 aid stations
  • Steep climb (10%+)
  • Climb (3-10%)
  • Flat
  • Descent
  • Steep descent (12%+)

The published GPX measures 22 km with 872 m of climbing, 39 m per km. The course sits between 466 m and 1104 m of altitude. 82% of the gain sits in the first half.

  • 0-8.2 km · Start → Zhongjunzhang: 429 m up / 19 m down; the stretch climbs.
  • 8.2-13 km · Zhongjunzhang → Niutou Village: 354 m up / 296 m down; the stretch keeps rolling.
  • 13-22 km · Niutou Village → Finish: 89 m up / 554 m down; the stretch descends.

The first 1.8 km are close to flat, good for settling in. Do not set your pace here, the real course starts after.

The backbone of the course runs from km 2 to km 10: 629 m over 8 km at 8% average, its steepest roughly 250 m section averaging 24%. Heaviest kilometres: km 9 187 m, km 5 105 m, km 7 100 m, km 8 95 m. This is hiking terrain, not running terrain. Walk it with intent and keep your heart rate off the ceiling.

The longest descent starts at km 15 and loses 538 m by km 22 at 8% average, its steepest roughly 250 m section averaging 25%. 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 10 averages 42% 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 2.7 km drop 88 m. If anything is left in your legs, spend it here.

  • The organiser lists 21.5 km; the published GPX measures 22.1 km. The technical course notes use the published GPX measurement.
  • This course reaches 1104 m. At the high-point coordinate, the same week historically ran 8°C to 15°C. Typical daily maximum wind was 12 km/h, reaching 32 km/h in the sample. This is climate history, not the race-day forecast; keep the shell accessible if race week looks similar.
  • Sunset is 18:02 and the finish cut-off is 14:30. A runner using the full time allowance spends the final 13 hours 16 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.
  • At cut-off pace you run into a second night. Plan the sleep question before race day: an hour gained on the first night costs two on the second.
  • Consider bringing poles. The course averages 39 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.
  • The climbing is stacked into the first half. Start easy; even with less climbing later, the descents and accumulated fatigue still have to be managed.
  • 14% 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.
