Designing an athletic track could get you as bored as when you are running on it: curve, straight, curve, straight, again and again...
Perfectly standardized, sport architecture has become more universal than international style. Track length of 400 m, 36.5 m radius. 1.22 m each lane....just data, without any fissure to let your imagination soar.

We have added to the conventional track an alternative one, amateur and funny, raised and tree-dimensional. It goes off on a tangent, covers the changing rooms and returns to the conventional track.
As new ways are available for athletes, spectators get involved in the sport activity, seated in-between this two tracks.
