ABOUT TRAILS & ALE
This intermediate/advanced level ride is a great mid-week tonic. Ride at your own pace and we’ll regroup at intersections. Explore trails that are new to you and find a new riding buddy or two. We'll plan to tailgate together at the end of the ride or go to a restaurant, see comments for picnicking details.
