Actually, that makes me wonder - and this has probably been answered already, so sorry - but how is the record holder determined? Let's imagine Tarzan, the hare (shouldn't that cheetah?) reaches 75,066 miles in, say, 300 days - does he then become the record holder until Steve, the tortoise (shouldn't that be some other creature? Tortoises don't have teeth, do they?) reaches 75,067 miles on day 364? Or do they have to ride for a full 365 days regardless of total reached?
(And what if IronOx fails to reach the Godwin Year but carries on and exceeds 100,000 miles in 500 days - because rust is slow but it never sleeps, remember?)
