With his Luxodrome concept, architect Charles Wagner has put forward a novel take on the cycling velodrome, with two tracks side by side with adjoining lanes that form one long figure eight track.
The Luxodrome consists of separate 200 m and 250 m tracks, the latter being the requisite length for an Olympic-spec velodrome track.
The connection between the tracks requires diverging lanes, similar to a freeway interchange. A bridge and underpass are needed where the tracks overlap, meaning that the track includes inclines.
How these unusual features would affect established cycling events is a point for further consideration, but as a playground for cycling enthusiasts, the Luxodrome looks like tremendous fun.
