Zube with NWCC is awesome. Groups, speeds, and personalities for everyone! Come out, have a blast, get 40 good miles in! Most of the groups go 40, though there is usually a 25 and sometimes a 50 or more. Eats and drinks at the end, free of charge. The no drop group is super accommodating, don't be scared if you haven't done many (or any, as was my case the first time) group riding before.
