The ride is flat, fun, and fast, making it perfect for riders of all levels, and there are 100-mile, 63-mile (Metric Century), and 37-mile courses.
The 3F Century is different than most bicycle centuries. It doesn’t have the heart-pounding, thigh-killing climbs that many centuries have. Instead of hills, hills, and more hills, the 3F Century offers a FLAT, as FAST as you want, and FUN bike ride. The total elevation gain is a mere 591 feet. Described in CycleCa magazine as one of the best rides for a first century. So if you are ready to tackle your first Century, Metric Century, or set a PR for a Century ride, then this one is for you.
