If it's 200 miles or more, it's a double century. And if it's 100 km or more, you can call it a metric century (which this thread is not about). Anything less and it's not a century or a double century, just like a run of 25 miles / 40 km is not a marathon but just a long distance run.
I think I get it! With your rules, all those slightly less than 100 mi. aren't centuries but for the doubles I do get credit for two centuries. Right?
I have no idea where the "90 mile" rule came from but it's accepted around here. For Los Angeles Wheelmen 90mi. or more can be counted and for the CAL Triple Crown (the double century org.) 190 or more is a double.
