This intermediate/advanced level ride is a great mid-week tonic. Ride at your own pace and we’ll regroup at intersections. This is a no-drop ride. We finish every ride by gathering at a local establishment for food and good cheer. Explore trails that are new to you and find a new riding buddy or two. Join the fun!

This week we will be riding at Betasso Preserve, an intermediate riding area. Expect flowing single track that is mostly easy, with some small embedded rocks and rooty areas, and few stiff pitches. Some trails are fairly narrow with exposure and may not be suitable for beginners. The full figure 8 route of both loops is a bit under 7 miles and 800 ft of elevation gain. Extra Benjamin loops can add to the fun and mileage.

Aerobic Difficulty: 5/10
Technical Difficulty: 4/10
