Bicycling/Tricycle racing games.
Can tricycle racing road games events be organised?.
Can tricycle racing games be considered in Olympic games?.
Thank you for your new question, I don't exactly understand what you mean with tricycle races?
But eventually Olympic disciplines are covered by the UCI (Union of Cyclist International), every discipline can be ridden if these are selected by the IOC (Internation Olympic Comite).
This means, that many races can be done but at the end the IOC all the disciplines on the Olympics. Sometimes new sports are shown as demonstrationsports, and some as Olympic disciplines.
Hope that this reply will answers your question.
If not, drop me an message with more details please.
