I live in central Connecticut and want to do an organized/charity/group ride every month next year starting around May and ending in October. I am looking for Centuries, Metric Centuries, or interesting group rides not less than about 50 miles in length. So far I have planned 1) the Bloomin' Metric in Norwalk CT, 2) the COVAC in Hatfield MA, 3) the D2R2 in Greenfield MA, and 4) the Flattest Century in the East in Tiverton RI.

Where can I find information on other organized rides in New England? Please suggest other interesting rides that I can investigate. — Thanks!
