I agree with McWin, I am for a Masters 35+ B category. I think that there are LOTOJA racers out there that would like to race other guys that lack the experience, and probably the time constraints to race a lot... and that is what it takes to be competitive in M35+, 45+, 55+.
The question is, should it be open to 3's, 4's and 5's or just 4's and 5's. I would bet that most 3's would do M35+, 45+ and 55+ except for some that haven't been training, and / or racing, and want to get back into it. Therefore the McCone "sandbagger policy" would correct that (really problably not a big issue).
As mentioned before the only fields that this would impact would be M35+ and maybe M55+. And even there, for the riders who are competitive, its not an issue to just have more riders line up if they are shot off on the first acceleration. Why don't we give it a try this year with a couple of larger races single day races, if the promotors are ok with it of course... why not it could bring in more cash, short and long term with just one more category. And if wheel cars are a problem, no wheel cars for the B's, no worries, they ride everyday without wheelcars already.
Not to put the cart before the horse... logitically speaking we need-
1. To amend the bylaws to have more time to look into this, if we want to try it this year.
2. Market this well within the racing community from all (current categorized racers all have friends they could recommend this category to who may have shown some interest, as well as teams, clubs, bike shops, Cycling Utah and even at the at the crit series events.
I agree with McCone in that it may be beneficial in increasing the pool of racers locally, and as always, some will move up and become the Cowleys, Louders, Schaeffers, Zimblemans and Claws (and many more who started racing at later ages) who could increase the already competitive masters fields.
That's all I have to give, my brain is smokin' from overuse.
Thanks to Claw and Mark for posting and everyone elses ideas. When trying something new... market, test and take baby steps... no worries.
