Didi Senft

Dieter "Didi" Senft is a German cycling fan who is known as the Didi the Devil or El Diablo at the Tour de France and Giro d'Italia. Since 1993, he has been seen in the Tour and Giro's many stages wearing his red devil costume and painting trident symbols on the road some miles before he appears. Senft said the inspiration for his costume came from secretly watching the Tour de France on West German TV and hearing a broadcaster refer to the red triangular flag that marks the last kilometer as "the devil's red flag."
