Sorry if it seems a bit obvious but I suffer badly with cold hands and feet in the winter months on the bike. A very simple solution I use (I'm thinking of you @slowmotion after the Brighton ride, I stuck some in my shoes in the Cafe at Crawley.) is the hot hands disposable hand warmers. Used to use them when playing golf but have started popping one in each shoe. You can get specific foot ones but the hand ones are larger providing moreheat for longer .
