It is to do 100km in a continuous single ride at least once a month. Whether it's allowed to be culmulative on the same day I'm not sure - the Imperial century challenge allows reasonable stops (say, a lunch break) within a ride but doesn't allow seperate rides morning and evening to count as one. However looking back at the original rules it doesn't specifically say that about the metric one.
What does everyone else reckon?
Ah - I couldn't find the "original rules" cheers.
NP.
I don't think I could add the extra klick or two to push it over the daily ton anyway
