When lord Coe announced the plans for the London 2012 Olympic stadium, critics described them as "wilfully lacklustre" - the shooting venue has reportedly been redesigned four times. And when the official 2012 Olympic logo was unveiled, critics said a child could do better.
Now pupils at two schools have taken up that challenge, winning an official competition to design an Olympic cycling venue.
St Robert of Newminster School in Tyne and Wear, and Curwen Primary School in Newham, east London, held off 500 other schools in a sprint finish to win the Olympic Delivery Authority's "VeloDream" competition.
Nobody will accuse their designs of being lacklustre: Curwen's bright blues and yellows were intended to be seen from space; St Robert's design features a domed roof that resembles the Earth.
So, given the quality of the children's designs, will Olympics organisers actually build them? Well, no, admits an Olympics spokesman - but the pupils will work with Hopkins Architects to design part of the Olympic cycle park.
