This was pointed out to me by some "Iron-Butt" riders and I checked my Geico policy and they were correct.
Exclusions:
(a) any hillclimbing exhibition;
(b) any race;
(c) any speed contest;
(d) any marathon-type contest;
and the one they were most concerned about
(e) any contest which sanctions continuous riding for 24 or more hours and/or mileage accumulation in excess of 500 miles per 24 hour period
I think it would still be OK to ride over 500 miles a day, as long as I'm not competing in any event
