If you're looking for a true test of your mountain biking skills, an XC course is the way to go. These courses typically consist of a mix of singletrack trails and fire roads, and can range in length from 5 to 50 miles. Some XC courses are even longer, making them true epics in the world of mountain biking.
The defining characteristic of an XC course is that it is designed to challenge all aspects of your riding. You'll need to be able to handle steep climbs, technical descents, and everything in between. Many XC courses also include features like log hops and creek crossings, which add an extra element of challenge (and fun!).
Whether you're looking to race or just ride for fun, tackling an XC course is a great way to step up your mountain biking game. And who knows, you might just find yourself hooked on this type of riding!
