Does anyone actually care where some people who are famous for nothing particularly useful actually live?
When they invent a cure for cancer a fuss may be due but riding bicycles.......!
(Ditto that dreadful woman who won something in the horse riding classes and who was interviewed without a mention for the efforts the horse had put in.)
Actually, I'm quite proud of the British cyclist achievements (in the Olympics and the Tour de France) and it certainly seems to have stimulated a healthy interest in cycling round here (and, I suspect, helped get some extra cycling routes). At least two medallists have lived / are living locally, and they train at the Manchester velodrome - which is open to all.
With regards to interviews after equestrian events, I think the BBC tends to address the rider because the horse isn't very good at speaking into the microphone.
If someone "invents" a cure for cancer I'm sure they will get their Nobel Prize. Until then, sporting achievements are well worth celebrating. To have beaten the rest of the world takes a lot of doing.
