Parkour in the mist

The symmetrical garden of the Assumburg Castle in Heemskerk. Training can be characterised by its symmetrical composition. To 'go the distance', say 10 K, requires to get back the same distance. This is where the benefit of training lies. Especially in the winter. You can't just stop. You will freeze. You have to keep moving to return. This is how endurance is built. There is no quitting option.
