Assuming you had the time/$$/mobility to do all the races in your local area/association, why not do as many as possible in a given season? (e.g. road race, crits, circuit races, both hilly and flat)
Seems like lower cats (3-5) can use all the racing experience they can get, and as such shouldn't be picky about what races they're doing. Yet I hear lots of beginners talk about "choosing their races".
How do you know you're not a sprinter if you've never tried to mix it up at the end of a crit? (e.g. just b/c you're skinny doesn't mean you should only do hilly RRs)
Maybe this is not as big of an issue way up here in WSBA, as we have at most 2 races on the weekends, and 2 training crits on weekdays during the season. But guys up here still talk about "choosing their races".. why?
Even if you're fat, you should still do that hilly road race! And skinny racers should show up to the flat crits.
[This is really just an attempt to get field sizes up, btw]
