A metric century is a 100 km ride which is popular with road bikers. At over 60 miles there is plenty of challenge in the length of this course, but that isn't all. The first 20 miles of this course offer a lot in the way of challenging climbs, which though not especially steep, are somewhat long sections that are sure to give you a workout. After the initial challenge of the first climb which rises over 500 feet, the back two thirds of this ride is a gentle downhill slope to make the finishing portions of this ride nice and easy.
