There is a jogging community at the hotel in Zhangjiakou where I stayed during the Olympics.
Joggers in hats and masks run up and down stairs in minus 20 degrees Celsius.
Their damp breath freezes the hats and masks.

Follow I follow
Much has been written about the lack of freedom of movement at the Olympic Games.
You can only take the bus.
But here the police and security officers just watch when the horde jogs past them.
There is a security officer there
I'm participating on my last day in Zhangjiakou.
Run up stairs, do laps in circles in front of a restaurant.
I follow another runner who turns towards the bus parking lot and goes around it.
The paths are limited, one lap up to the bus, down the stairs again, and up again.
After the second flight of stairs I discover a path, footprints in the snow.
Can I do a little extra lap there?
I follow the tracks, turn a corner.
A security officer is standing there with his leg stretched out on a windowsill.
Next to him a policeman.
They wave at me - because they really have nothing against movement.
