Australia has some great masters racing, and in fact there is a masters racing association totally separate from Cycling Australia because in the past masters were always getting treated as "add ons" to racing programs. It is a really good organization for riders 35yrs & above, with good regular racing both handicapped & age graded. I did a series of masters races (50-55yr category) at the Tour Down Under a few years ago & got smashed big time, which may have been due to the presence an Olympic medal winner from LA games & a former Aus national champion in the peletons, but the racing was great.
Amateur racing & masters racing on such a grand scale will probably be unmanageable, perhaps unfair, by the UCI (again see my post in the clinic).
$$$$'s will be a factor, it's a factor in pro racing, in-fact its a factor in life, the guys/girls with the best financial backing, be it from mum & dad or perhaps the company one runs/own or from just the good old trust fund.
But all in all it will be another racing format that we can all watch, follow, maybe race in, or maybe just comment from afar.
