Running alternately uphill and downhill in high altitudes is a particularly strenuous and grueling challenge for the human body. So, it didn't take long for the line of runners to stretch out longer and longer. Also, the section up to the summit of Mt. Hohuan is very difficult, due partly to the steepness of the grade and partly to the loose gravel on the road. The course at that point rises 146 meters in just one kilometer. The new route is widely praised for its challenging degree of difficulty, and for the location's beautiful scenery and relative convenience.
People assume that running down steep slopes is easier than running up, but it is equally difficult.
Running alternately uphill and downhill in high altitudes is a particularly strenuous and grueling challenge for the human body. About 750 contestants showed up, accompanied by an equal number of cheerleaders. The race was served by a large and friendly staff. The multitude made this otherwise remote area deep in the mountains an audacious, bustling place. All the runners seemed well prepared on this early Sunday morning.
