Two 50s do not make a multi-day ride;
multi-day rides require at least 3 consecutive days of 50 miles or greater (some
are 55 or even up to 65). Whether or not 2 days of 50 mile rides is
considered a 2-day 100 is dependent on what the ride manager calls it. If
it's to be a 2-day 100, it must be listed that way in the sanctioning
request.
