Olympic/International Distance Races in North East

[ChronoFish]

Hi There,

To save me the trouble of looking up past results from several dozen
races, I thought I would ask here.

Do you know which Olympic/International Distance races in the North
East area (Northern Pennsylvania, New Jersey, New York, Connecticut,
Rhode Island, Massachusetts, New Hampshire, Vermont, Maine) have
500-700 competitors?

I'm not looking for huge races like the New York City Triathlon. The
closer to 500 the better.

So far I've got one on my list - Cranberry Country Triathlon in Mass
(490).

Thanks!
CF
