Any reason why 'green' is exempt from mudguards compared to the other three routes?
Because I forgot to include the 'M' in the event registration, however it will be recommended in the info sheet. These are winter rides on some roads that may suffer from the consequences of inclement weather. At the risk of opening the debate of compulsory mudguards again - for my part as the organiser of the Yellow and Green rides I would prefer that bikes have mudguards for the courtesy of pubs and cafes that may be visited; for other riders in a group, everyone is adult and can chose to ride with whom and where they like, I'll choose to not ride behind an unprotected rear wheel that is making me wetter than I'm getting from above.
I will not be enforcing compulsory mudguards at the start but would hope everyone extends the courtesy that they would wish to receive themselves. After all, it's not compulsory to sit on upholstered chairs at a commercial control, other options are available.
