Gongga 100: What Is It Really Like to Race in China’s High Mountains?
Glaciers, 4,500-metre peaks, deep mud, unpredictable mountain weather and a race atmosphere unlike many European trail events - Gongga 100 is a very different kind of trail-running experience.
For international runners, travelling to China to race Gongga 100 means stepping
well outside the familiar.
The FUGA Glacier Extreme Gongga 100 takes place in the Hailuogou Scenic Area,
at the foot of Mount Gongga (Minya Konka), in Sichuan. Its routes pass through
glacier and high-altitude alpine terrain, with sections above 3,500 metres. The 100K
covers more than 100 kilometres and climbs over 7,000 metres.
But numbers only tell part of the story.
To understand what Gongga 100 is really like, we spoke to runners who experienced
it first-hand — including the Belgian winner of the women’s 40K, Chinese runners
who know the local trail scene, and Korean runner Jung Filhwa, whose attempt at the
100K brought him face-to-face with the extreme altitude of the course.
A race that feels different from the start
For Vanja Cnops, the Belgian runner who won the women’s 40K, Gongga 100 immediately felt different from the European races she is used to. For international runners interested in trail running in China, understanding these differences is part of preparing for the experience.
Although Vanja has lived in Asia for almost 15 years, racing in China was still
relatively new to her. Getting to the race town went smoothly and was easier than she
expected. While not everyone spoke English, she found that there were always
people around willing to help whenever she needed directions.
Then came race day.
The atmosphere was one of the things that immediately stood out.
The race started with a large stage, big screens and a full sound and light show,
creating a real sense of anticipation before the runners set off.
The presentation of the top-ranked runners before the race, as well as interviews with
runners at the finish, were also things Vanja had not experienced at a race before.
For her, Gongga 100 offered a very different atmosphere from most of the races she
had experienced in Europe.
“The Chinese also know how to put on a great show.”
And that difference begins before runners even reach the mountains.
Into the glacier landscape
The spectacular environment is perhaps the biggest attraction of Gongga 100.
According to Jason Gu, a Chinese runner who has raced other trail events in China,
the snow mountains and glaciers are what really set Gongga 100 apart.
“You’re not just looking at Mount Gongga from a distance — you’re actually racing
deep in the mountains.”
The longer courses take runners into glacial terrain, creating an experience that is
difficult to replicate in a conventional trail race.
The race starts and finishes at Hailuogou Scenic Area, on the eastern slope of Mount
Gongga. The area is known for its glacier landscape and views of the Gongga
massif, which rises to 7,556 metres.
And the glacier experience begins even before race day for some runners.
In his race report, Korean runner Jung Filhwa describes taking a cable car into the
glacier landscape at around 3,500 metres before the race. He also had to prepare a
separate drop bag containing equipment such as his helmet and crampons for the
glacier section.
For runners used to European mountain races, it is difficult to imagine a more
unusual race environment.
But the mountains come with a price
The scenery is spectacular, but Gongga 100 is not an easy race.
High altitude, steep climbs, technical terrain, mud and changing weather all combine
to make the course demanding.
Jason highlights the combination of factors:
“High altitude, steep terrain, technical sections, and unpredictable mountain weather
all come together.”
Vanja experienced some of that difficulty first-hand during the 40K.
The biggest challenge for her was a huge 1,000-metre climb to the highest point of
the race. The altitude was difficult enough, but deep mud made the climb even
harder.
“I was constantly looking for somewhere to place my feet without slipping back
down.”
The descent, fortunately, was considerably less muddy — and became one of her
favourite parts of the race.
When altitude becomes the real challenge
Jung Filhwa’s experience provides an even clearer illustration of just how serious the altitude can become on the 100K.
The course took him over two peaks at around 4,500 metres. He was able to
maintain a steady pace through the mid-3,000-metre range, but once he climbed
beyond 4,000 metres, he began experiencing severe symptoms of altitude sickness,
including a splitting headache, nausea, hyperventilation and repeated vomiting.
After reaching one of the 4,500-metre points, he still had to descend while remaining
above 4,000 metres. At a checkpoint between the peaks, he explained his symptoms
to race staff, who provided him with oxygen and a warm drink.
Receiving oxygen meant an automatic DNF under the race rules, but at that altitude,
safety had to come first.
Jung still had another 4,500-metre peak to cross before reaching the next
checkpoint. With the help of oxygen, he continued forward, taking extremely small
steps. According to his report, it took him seven hours to cover the final four
kilometres of that section.
Eventually, once he descended below 4,000 metres, his condition began to improve.
His race had ended, but the experience left him with an extraordinary memory.
The scenery was, in his words, the best view of his life.
It is a powerful illustration of what makes Gongga 100 so unusual: the same altitude
that creates one of the race’s biggest challenges also creates some of its most
spectacular scenery.
Prepare for changing conditions
Jung’s experience is extreme, but other runners also highlighted the need to adapt
constantly to the mountain conditions.
Cristiano Xiao, a Chinese runner, points out that the course can change dramatically
in altitude, terrain and weather.
One section can feel relatively runnable before suddenly becoming a much steeper
climb or a technical descent.
His advice to international runners is therefore not to become too attached to a
particular pace.
Instead, runners need to keep adjusting their effort according to how their body feels.
At Gongga 100, the mountain ultimately dictates the pace.
And weather can change that equation even further.
Jung’s race started at midnight in pouring rain. The first section was relatively
straightforward, but the rain quickly transformed the trail into deep mud. His shoes
became covered in mud almost immediately, making the early stages even more
demanding.
Nutrition at altitude: expect something different
Altitude can also affect another essential part of an ultra: eating and drinking.
Cristiano points out that runners may find their appetite reduced at altitude. Foods
and gels that normally work perfectly during a European trail race can suddenly
become much harder to consume.
There is also a cultural difference at the aid stations.
International runners may encounter more hot food and local options than they are
used to.
His advice is practical: find out in advance what will be available and bring some
familiar food that you already know works for you.
For a long race at altitude, nutrition should be part of the preparation rather than
something left to chance.
Good shoes, pole- and an open mind
Vanja’s advice for runners considering Gongga 100 is refreshingly simple:
“Bring trail shoes with good grip, bring some poles and bring an open mind”.
That last point may be the most important.
Gongga 100 is not an easy race, particularly over the longer distances. Vanja
suggests thinking of it as an adventure rather than simply another race to be
completed.
The race itself is only part of the experience.
A race with serious preparation requirements
The organisation also reflects the environment in which the race takes place.
For the 100K, mandatory equipment includes a waterproof jacket, thermal layers,
waterproof and thermal trousers, headlamps, navigation equipment, emergency
equipment and other cold-weather gear.
Runners must also carry crampons, a climbing helmet and poles on the 100K.
Equipment is checked before the race and spot checks can take place during the
event.
The entry requirements for the 100K also reflect the difficulty of the course: runners
need either a recent 60K+ trail-race finish combined with experience above 3,500
metres, or a recent 100K+ trail-race finish.
In other words, this is not a race where you simply turn up with your normal ultra kit.
The organisers are asking runners to be prepared for a genuine high-altitude
mountain environment.
More than just a race
Yet for all the discussion about altitude, mud and technical terrain, some of the most
memorable moments can happen away from the course itself.
Vanja was particularly struck by the local people in the mountain town.
She felt that many of them probably don’t get many visitors from outside China, yet
they were incredibly welcoming.
Along the course, runners were greeted with plenty of enthusiastic “Hello!” and “Jia
you!”
Chinese words of encouragement meaning “keep going!”
For an international runner who has travelled thousands of kilometres to race in
China, those moments can become just as memorable as the mountains themselves.
So, what is Gongga 100 really like?
The answer depends on what you are looking for.
If you want a familiar European-style trail race with predictable conditions and an
environment you already know, Gongga 100 may not be the obvious choice.
But if you want adventure, spectacular mountains, glaciers, high-altitude racing and
the chance to discover a very different trail-running culture, it is a fascinating
proposition.
The experiences of the runners we spoke to paint a consistent picture.
Vanja found an event with a spectacular atmosphere and a welcoming local
community.
Jason sees the snow mountains and glaciers as what truly separates Gongga 100
from other Chinese trail races.
Cristiano highlights the importance of adapting to altitude, terrain, weather and
nutrition.
And Jung’s 100K experience demonstrates just how seriously runners need to
respect the alti- while also showing why the scenery can be so extraordinary.
Put all of that together, and Gongga 100 feels less like a conventional trail race and
more like a mountain adventure that happens to be a race.
