Sign up and start entering your 2018 centuries.
A metric century is 100 km, or 62.14 miles. All of your metric centuries completed during the year count, whether they're official club rides, solo rides, or big-event metric centuries. A double metric century (124.3 miles) counts as two metric centuries. While the goal is 100 kilometers, we will accept rides that are close but perhaps two or three km short, especially if the ride in question is very difficult. It's an honor system: if you're comfortable listing it, that's all that matters.
