Gaoligong Ultra

Report by Gabriel Green, more details at Miles Ahead

Gabriel Green, an American runner, completed the 2026 Mt. Gaoligong MGU 168km in 46 hours. He was kind enough to share his race report with RunEast, and we are pleased to present it here.

TL;DR: Went to China to run one of the most technical ultras I've ever done with my dad and a group of fellow American ultrarunners. My dad got pulled by medics at mile 65. I nearly DNF'd at CP11 alone and hallucinating. Finished in the rain with four other Americans and I'll never forget it. Here's everything I learned.

Background

I was invited to run as part of a group of 10 elite American ultrarunners. The race itself is part of an ambitious project to connect the full 300K Gaoligong mountain ranges - this 168K is one piece of that vision. The race village, ceremonies, and production quality of this race was incredible. This is not a small local race. It felt like a world-class event.

The course starts and finishes in Tengchong, a city in Yunnan province near the Myanmar border. The terrain is relentlessly technical - steep, rooted, often slick - with sections of jungle descent, open ridge lines, river valley crossings, and everything in between.

Logistics - What to Know Before You Go

Getting there: Fly into Tengchong Tuofeng Airport (TNH). It's a small airport but well connected through Kunming. Budget at least 2 extra travel day on each end.

Drop bags: Available at CP7, the first major reset point - we used it for a 30-minute sleep, sock change, and food reset. Also available at CP12, where I used it for a 20-minute nap and shoe change. Plan both intentionally.

Aid station food: Almost entirely noodles, rice, broth, buns, banans, oranges, watermelon, Snickers, & some. It's good, it's warm, and it works. But if your stomach turns on you mid-race and you can't face noodles, you need a backup plan. I survived on bananas, rice and what I brought from home once I couldn't take down noodles.

Cutoffs: There are hard cutoffs at CP4, CP7, CP9, CP12, & CP15 with 47 hour finish cutoff. They're enforced. Volunteers will pull your bib. Build your pacing plan around CP9 (the most people I saw eliminated) and CP12 (the one I nearly missed).

Weather: We got hammered with rain starting around hour 36. Everything got soaked. Make sure you're covered on waterproof gear.

Gear & Nutrition - What Worked, What Didn't

They do have a mandatory gear list similar to that of a UTMB race.

What worked:

• Poles (essential for the climbs and descents)

• Waterproof shell

• Ideally 30-minute sleep strategy (two naps total - CP7 and CP13 - both critical)

• Gaiters

What I'd change:

• Backup nutrition for aid station incompatibility. When noodles aren't happening, you need something. I thankfully brought nutrition with me from the States.

• An extra dry bag for socks and a mid-layer. Everything was soaked by hour 36 and stayed that way.

• More aggressive sleep planning. Two 20-minute naps over 45 hours works but it's the floor, not the ceiling.

On sleep deprivation: This will define your race more than fitness. By night two I was full hallucinating - trees as people, leaves with faces, course markers that looked like strangers. I was walking in zig-zags. So was everyone around me. It's not a sign something is wrong; it's the race. Have a plan for it. Caffeine helped. Music helped more. Having another person helped most. Sleeping for 20 minutes at a time at aid stations was the best.

Mental Strategy - The DNF Decision

This is the part I want people to really sit with.

At CP11, around hour 36, alone, hallucinating, with my dad just pulled from the race by medics, I sat down and genuinely thought I was done. I had nothing to prove. The original goal - finish with my dad - was gone. I called him and told him I was thinking about dropping.

What pulled me back was a friend ahead of me, and I asked him specifically what the next segment looked like. He gave me a concrete answer: brutal climb out, then runnable fire road, 2:15 total. I had 3 hours to the cutoff.

That's it. That's what changed everything.

The lesson: When you're considering a DNF mid-race, don't make the decision in a vacuum. Get information first. Talk to someone. Ask what the next segment actually looks like before you quit. Take it one checkpoint at a time.

Final Thoughts

This race is legitimately one of the hardest things I've done. The terrain, the cutoffs, the logistics of running in a foreign country, the sleep deprivation, 8PM start time - it compounds in ways that are hard to prepare for fully. But the organization is world-class, the volunteers are extraordinary, and the course will show you something about yourself that flatter races can't.

If you're considering it: go. Learn a little Mandarin (learn what jiayou means). Bring backup food. Have a sleep strategy. Don't decide to DNF without information. And stay open to whoever ends up next to you on the trail.
