Taiwan’s KOM Challenge is one of many cycling events in Taiwan. This professional race, which is recognized as one of the toughest in the world, sees athletes racing to climb from directly through Taroko Gorge to 3275 meters elevation just under the summit of Mt. Hehuan. The course starts at sea level in Hualien and follows the Central Cross-Island Highway. While the physical demands of the race might exceed the abilities of most, the first 20 kilometers of Taroko Gorge are relatively flat and are a great option for a half-day cycling tour for regular tourists.
