Rides great in both directions.

North to South - a few fun, but punchy, technical uphills when riding in this direction finishing with a fast, flowing downhill.

South to North - starts with a more gradual climb up. You won't avoid all the punchy ascents as there are still one or two mixed in. Multiple opportunities for drops/rollers when riding south to north.
