Just as a supplementary answer to Sarah’s to idroolinmysleep’s question regarding musette contents, this is a picture of some of the stuff discarded by riders during Stage 3 of the Tour of Britain last year.
My boyfriend and I decided to hang about the feed station with our ideal goal of obtaining a musette. It didn’t happen (one day…) but they were lots of discarded bidons and food stuffs. Mainly a lot of energy gels and bars, but also small cans of coke, sandwiches and in one case a brioche with ham - I assume that perhaps belonged to one of the french teams ;)
