Yading Skyrun: Hongkongers suffer at altitude as ‘muscles don’t work’, but complete epic mountainous race
- Ethan Ko Man-ho and friends slog through 32km race in beautiful mountains, realising China has nothing to envy in the European Alps
- He feels free running in Sichuan, but it takes a few days of feeling down with lack of oxygen

Ethan Ko Man-ho stepped off the plane in Doacheng, the world’s highest airport at 4,411 metres, and immediately gasped for air.
Ko and friends Leo Hui and Suki Yiu and other Hongkongers were there for the 32-kilometre Yading Skyrun, but the 4,700m-high course took its toll on the group.
“The altitude is something we expected would hurt us,” Ko said. “But when we touched down at the airport, at over 4,000m, we thought ‘help’. When we got up to the mountains, our muscles just didn’t really work any more.”
After a couple of days acclimatising before the race, Ko said he felt “really free”, but even with the time spent adjusting the course was punishing.
“We went very slowly as we were all out of breath. The muscles don’t have that oxygen level [needed] to work,” he said.
