I think Geraint has the making of the best all round road cyclist of this generation and a high position overall.
IF - he'd look at the Gold medals he has and realise that in Road cycling the Olympics are not top dog. How often are Olympic gold winners talked about in Road Race circles, compared to Milan-San Remo/Paris-Roubaix/Flanders etc.
It's his choice and maybe a reflection of where British cycling is coming from but personally I see next year as a "waste" of a year of road experience (and wins) IMHO.
As said though, it's his life and nothing to do with me.
