“A demanding climb that eases up around the next corner... or is it the next one?”— Dan Oakland
The Harding Truck Trail lives up to its name - it's hard. It's a truck trail / fire road the whole way up. Although wide, it does have more of a double or even singletrack feel than most OC Fireroads. One side will be more dominant than the other. Unlike Maple Springs Rd (the most common way to reach 4 Corners) you'll not experience vehicle traffic on Harding unless there is an event scheduled that day. It's a popular trail-running route. The trail will also stay hard-packed throughout the year and holds up against rain fairly well other than the first 2 miles. It's definitely more challenging though.
At the 7-mile mark you'll get a much-appreciated reprieve from the (average 8+%) climbing for about 3/4 of a mile before the last 1.5 mile charge up to 4 Corners. From 4 Corners you can head down to Maple Springs and road-ride back to your car, head up to Modjeska, Santiago Peaks, Joplin trail, Silverado Motorway, or simply back down Harding.
Coming back down is quick, with many water-bars available if you like to jump. Keep your speed in check for trail conditions, blind turns, and uphill riders and trail runners who will likely use the dominant track.
