This is a 23 mile approx. ride with STEEP hills, but after the hard work the return to just south of the river is mostly a downhill breeze. http://www.mapmyride.com/us/austin-tx/hills-route-141039501 (Exact route could change slightly.) I am a B/B- rider. This ride is for those that feel good about being able to make it up these hills on Lost Creek Blvd. without stopping, not so much for those that think you should be able to go up the hills and go fast at the same time! No drop if you end up walking the worst parts. :)
We could also continue right on Barton Creek to a serious hill right before Bee Caves and then loop back which would give us a stop at the very friendly Lola Savannah coffee shop on Bee Caves.
