running up that hill.

Hong Kong Island is dominated by steep, hilly terrain, which makes it the home of some rather unusual methods of transport up and down the slopes.
I'm amazed that outdoor escalators even exist! 

•  In the Central and Western district, there is a huge system of free escalators and moving pavements. 
• The Mid-levels Escalator is the longest outdoor covered escalator system in the world
• it operates downhill until 10 am for commuters going to work, and then operates uphill until midnight.
• The Mid-levels Escalator consists of 20 escalators and 3 moving pavements.
•  It is 800 metres long, and climbs 135 vertical metres.
•  travel time is approximately 25 minutes, but most people walk while the escalator moves to shorten the travel time. 
• Due to its vertical climb, the same distance is equivalent to several miles of zigzagging roads if travelled by car. 
• 35,000 people use it everyday! thats equivalent to half the population.
