Designed and built by local legend Shaggy with help from local volunteers, Third Circuit is a 0.4 mile Black Diamond downhill mountain bike only singletrack trail. The name honors William Hastie who was appointed to the US court of Appeals for the Third Circuit, making him the first African-American federal appellate judge. Tight, narrow and with several technical gaps, moderate rock drops, rock gardens, catch berms, and steep rock rolls, it is a fast-paced firecracker of a trail. Abundant wildflowers line the trail in spring and if you're lucky you may see an owl or two. The trail begins at the top of Remedy Hill and intersects with Spingarn, taking riders back out to Margaret Rd and the main parking area or back up for another session.

Best technical descent in the area. Covered in leaves in the fall bet it's a dream in the spring.

My favorite descent in Knoxville. Thank you to the builders, this trail is genius!
steelispossiblyreal
This is one of the best descents in Knoxville IMO. Shaggy and co you knocked it out of the park!
We hope you've been enjoying Trailforks!
