Course or Race Highlight
Pleasant Ridge County Park sits up against the Blue Ridge escarpment, and the trail through Camp Spearhead is the kind of singletrack that rewards rhythm over raw speed — rolling, shaded, and consistently runnable, with 650 feet of gain per lap that arrives in pieces rather than one long wall. Directional arrows will guide your path, so you can spend the day looking at the woods instead of hunting for markers.
One stellar aid station sits at the main shelter and you hit it every loop. Afterward: music, a post-race party, event-themed giveaways, and a race sticker with rainbow flair for your bottle, cooler, or gear bin. The first 100 participants get custom race socks. Every finisher receives a medal, and your entry supports local nonprofits through the Giving Series.
