If it was "regomaniac”, that might well have described some behaviors of my earlier days.
Now, it's actually "regomatic", taken from "vegomatic" (you'll have to look it up). It's a nickname given to me from friends / work associates.
It started as a reference to a reputation of “can do” attitude and resourceful reliability. I try to live up to the same rep by setting and maintaining a steady pace and smooth line on the bike every weekend.
