The Crooked Feed for Le Tour:
After yesterdays stage two riders were each fined 100 Swiss francs (approx AUD$100) by the UCI for public urination and two others were each fined 30 Swiss francs for throwing bidons. The UCI would make a fortune if they policed this as thoroughly.
I couldn't find any reference to urination in the UCI rules but on drink bottles they say "Riders may not, without due care, jettison food, bonk-bags, feeding bottles, clothes, etc. in any place whatsoever. Riders may not jettison anything on the roadway itself but shall draw to the side of the road and safely deposit the object there." See
here. For the uninitiated, a bonk-bag is a feed bag.
